> One big area where modular prefab can potentially make a difference is by reducing the need for skilled tradesmen, particularly electricians, plumbers and HVAC techs.

To what end? As a country we're already struggling to create enough middle-class jobs and you're suggesting we try to gut another whole sector. So that owners/executives of prefab factories can pocket the money?

If you think it's going to reduce cost or benefit the consumer, you're crazy.

I notice you downvoted without responding. I presume you've got a plan to recreate those jobs vs. just transferring wealth upwards and are keeping it a secret.

It astounds me people on HN think that eliminating jobs without any thought to the social impact is somehow a righteous goal to strive for. Yet you can't even answer what the benefit is to society other than making some really rich dude a little bit richer at the expensive of hundreds of thousands of middle class jobs. And most likely an end product for consumers that's LOWER quality.

This is the fallacy - The Fallacy - that is always made by those who don’t understand economics.

Why did we build the car when it put all of the horse tradesmen out of business? Why do we use elevator buttons and put the doormen out of a job? Why did we create the Internet when perfectly good newspaper printers could pass information to us?

You are making an age-old argument that we need to reduce productivity in order to save jobs. If you spent your whole life scrubbing a floor with a tooth brush when right next to you is a mop, just so you can ensure more of your time was spent washing, wouldn’t you feel like your life was wasted?

I think your example isn't completely off the mark, but I do think the article itself actually answers this: there is a shortage in trade labour in the non-commercial construction sector in (North) America.

We are also at a cross-roads with regards to having a housing crisis. There are many places now (Bay Area, Boulder) where housing is skyrocketing not because the value is naturally increasing, but is instead being artificially inflated due to a shortage in homes. One "radical" solution to this: build more homes.

However, given the amount of labour and time needed to do so, we may not be able to avoid the housing crisis. One way the market is responding is moving to pre-fab construction, and trying to reduce time / costs that way. The article does seem to claim that the projects cost about the same, even if pre-fab is faster in terms of time. This _does_ identify a problem with pre-fab, namely, how come they can't fulfill this promise of being cheaper & faster. Seems strange that you save time but still cost the same when what you're proposing is taking away a significant chunk of higher-skilled labour from the equation.

Some of this is regulatory capture (wasted time / money trying to convince cities of the process), some of this is nascent technology sucking (see top parent comment, sometimes pre-fab doesn't get it right), and some of this seems to just be a lack of experience on behalf of the companies trying to "disrupt" construction.

The housing affordability crisis is caused by a set of polices designed to protect the equity of existing property holders by artificially constraining new housing supply and allowing a non-trivial numbers of properties to be removed from the long-term housing market by sitting unoccupied or being abused as short term rentals.

Further affordability pressure is also caused by the proceeds of corruption and organized crime being used to buy/hold housing as part of money laundering schemes. The sums of criminal money involved in the housing market are non-trivial and have been estimated to account for upwards of 5% of housing valuation in some cities.

Construction costs do not enter into this at all.

If you want to address housing affordability, only three things will make a difference: get rid of NIMBY vetoes on new construction, require all properties that are not owner-occupied to be tenanted, and severely crack down on money laundering through the real estate market.

Re:Why hasn't prefab construction taken over? by someguydave on Monday October 12, 2020 @09:47PM (#24761480)
The "housing crisis" is all about regulatory capture of local zoning laws and local oligopolies over development. None of that has anything to do with construction efficiency, which is already using "prefab" in the sense that the stud walls and roof trusses are already prefabbed offsite. Not to mention non-commercial construction tends to employ a large illegal immigrant labor population, which tends to reduce relative wages.
Re:Why hasn't prefab construction taken over? by bobthepanda on Monday October 12, 2020 @07:45PM (#24760796)
I don't know that you could avoid the crunch. Markets take time to respond to things, and the kind of housing that is prohibited, multifamily and anything >2 stories, is one where you progressively need more and more specialized tradesmen.

The US used to have prefab apartment block construction, as did most Western public housing programs, but generally speaking they have not held up over time.

This is potentially very much like saying, "we burned this little bit of fuel, and all that happened was the fire got brighter because it spread to more fuel! It can never go out!".

There's no reason to expect the job-generation cycle to last forever. In fact there's every reason to believe it can't. The question is whether it ends on a scale more like decades or centuries. To blindly assume that things will continue as they have is foolish. (To be clear, I think the solution looks more like UBI than Luddism.)

Re:Why hasn't prefab construction taken over? by marcusverus on Monday October 12, 2020 @07:49PM (#24760832)
I agree that the job-generation cycle may not last forever. But in order to oppose new tech as a bad thing right now, you have to make the case that the job-generation cycle is broken right now.

Arguing against new tech now because of some inevitable eventual breakdown of the job-generation cycle is just luddism with extra steps.

I think there is something to be said here. The car is a superior technology to a horse, but in many ways a prefab house is an inferior product. It's a regression, built from a need for skilled tradesmen and a lack of this labor supply.

I think a better way around that need would be to bolster training of skilled people which would lead to increased labor supply to meet this demand, rather than trying to figure out how to wring the last dime out of everything.

There was a story once told by Eric Schmidt that while on a trip to China he was touring a bridge construction and no heavy machinery was being used, the Chinese officials were pointing it out as something positive because it meant more people worked at the site and it generated more jobs.

Eric said they should have given the workers spoons if that was the goal, which caused a couple laughs that were met with anxious stares by local officials.

Large steel bridge construction involves much hand labor. Here's a big job in China.[1] If you're not seeing the foundation work or crane work, it may look like it's all hand labor. Large bridges are custom-designed prefabs. Somewhere else, there's a factory making the parts.

The defense industrial complex is the go-to, but I got a kind of novel jobs program that doesn't get thrown around a lot: Private Health Insurance.

There's a straightforward transaction that occurs between healthcare provider and patient. But every...single...dollar that flows through the healthcare system is diverted through the massive private health insurance industry, which is essentially an artificial middleman skimming money off the top of the transaction between healthcare provider and patient. This provides employment for millions of accountants, and MBAs, and marketing people, and database engineers, and statisticians, and lobbyists, and etc.

It's the more touchy-feely cousin of the Defense Industrial Complex that must vacuum up money somewhere in the same order of magnitude.

In places with, relatively speaking, rich social services programs are essentially jobs programs. The budgets are caseloads are never reflective of need, and most families would be better served with getting a check than meeting with a burnt/checked out social worker. Often times programs run by the state are so taxed that they are entirely incapable of meeting the metrics required by law.

Those trillions would have been better spent expanding government programs in: land preservation, social services, healthcare, stem, and infrastructure maintenance and expansion. Instead it's just sloshing around the accounts of people who neither understand nor care about the plights of the average American.

Re:Why hasn't prefab construction taken over? by tw04 on Monday October 12, 2020 @06:35PM (#24760246)
I see you ALSO failed to explain what the replacement jobs for these highly skilled, well-paid employees will be.

Horse tradesman became car dealerships. Elevator operator was never a skilled position in the first place. The internet has actually created a massive crisis in the western world that we're just now starting to realize - local newspapers going out of business is HORRIBLE for a functioning democracy, and nations across the globe are suing companies like google because of it.

You're insinuating that there will somehow be a new job for the folks put out of work, but fail to explain what that is. Look no further than Detroit, hundreds of thousands of middle class jobs that are simply gone. More weight on the economy, fewer middle class citizens, but a handful of shareholders and executives that are significantly more wealthy.

While I appreciate the condescending tone, I don't think you've even begun to put critical thinking skills to the problem. You're just parroting the same old tired story that justified "trick down economics" which is also based on a reality that doesn't exist.

Re:Why hasn't prefab construction taken over? by seibelj on Monday October 12, 2020 @06:55PM (#24760452)
What’s better - everyone who lost their jobs picks a new career and retrains doing something new that is valued by society, or the government subsidizes unvalued industries that no one wants just so people never experience any pain?

I’m sympathetic that government can help those who lose jobs. My preference is straight-up cash transfers so they can pick their own schools and move to where jobs are, rather than a government-run school loaded with bureaucracy. But artificially preserving shrinking industries just so we can all act like we still need them around is a waste of tax dollars and is logically inconsistent.

Re:Why hasn't prefab construction taken over? by tw04 on Monday October 12, 2020 @09:39PM (#24761442)
You keep downvoting me, but you’ve yet to explain where these jobs are coming from. The jobs Detroit lost didn’t shift, they were just lost forever. The people who held them now work minimum wage jobs or live off welfare. What are the electricians and plumbers doing instead? You can keep saying people will just retrain and do something else but that’s about as useful as Trump saying he’ll bring manufacturing jobs back to the US without any plan. The end result is a lot of nothing.
Re:Why hasn't prefab construction taken over? by seibelj on Monday October 12, 2020 @10:11PM (#24761593)
I’m not downvoting you - on HN you can’t downvote someone you are replying to. It’s the rest of HN that is downvoting your arguments.

Tons of jobs we have now didn’t exist 5, 10, 25 years ago. Every time a mass amount of jobs are lost when an industry collapses, they always say “this time is different!” I just fundamentally disagree with that premise. There will always be work to do and someone willing to pay for it. If that ceases to be the case it would be the first time in human history, which seems way less likely than society continuing on like it has for millennia.

You also seem to think individuals are too stupid to look at the job market, see what skills are in demand, and self-select for learning a skill that they will enjoy and get compensated a fair wage to them. Every single person who loses a job, provided they eventually get off the government dole, will have to find something new to do. Working for a while at a restaurant or warehouse isn’t something they have to do forever. There is just a distinct lack of belief in human agency in your postings.

Re:Why hasn't prefab construction taken over? by phobosanomaly on Monday October 12, 2020 @11:32PM (#24761998)
I think the sentiment you are responding to is the erosion of good jobs. There are tons of new jobs, but for those impacted by this stuff very few of them are good jobs that pay a middle-class income (I know, I don't have a cite, but I'm explaining a sentiment, not a fact - so iono I don't got it).

A contractor in a town where the jobs dried up might work at Lowe's now for example, where they would be kept under 20 hours a week so Lowe's doesn't have to pay benefits, and they could look forward to living in a van off of social security when they retire (source - this is my brother in law at 55 y/o - he has no idea how computers work, and desperately just wants to go back to laying tile like he did for most of his life - lost work - got a job at Lowes a few years back - just laid off actually, due to the virus - he's 100% screwed). There are a lot of these folks floating around, and what has happened to them is absolutely tragic.

Ideally he should re-train in something, but what often winds up happening is that they get sucked into for-profit colleges that encourage them to take out predatory high-interest loans for training that lead to job markets that are either oversaturated, or misrepresented. Then come the payday loans, then come the repossessions.

Ideally those people would just buy a bunch of NoStarch books and become fullstack developers or something, but that's not how people work, unfortunately and we just haven't figured out a good mechanism to help keep those folks on their feet.

The person you're responding to is waaaaaay too angry, and I don't believe you deserve to be on the receiving-end of that, but they may be going through some really rough stuff right now. There's a lot of people who have suddenly found themselves unemployed and homeless and they may very well be in that situation.

Re:Why hasn't prefab construction taken over? by tw04 on Tuesday October 13, 2020 @09:23AM (#24765315)
So what replaced the jobs in Detroit? You keep saying this but the numbers don't reflect what you're claiming. The middle class in the US is SHRINKING, their wealth is decreasing, and it has been since the 70s. All those jobs are going to other countries or disappearing entirely. You and everyone else on HN can keep parroting the same "it's different jobs" until you're blue in the face, but until you can show me some actual DATA to backup the claim, you're literally just making up a reality that doesn't exist. You're 4 responses in yet without a single citation to back up your claim that there are new jobs to replace the old, and I'm willing to bet if you replied 20 more times you STILL wouldn't have any facts to back anything up you've said. Going from a manufacturing job making $60-80k+/year to driving Uber making minimum wage isn't a "replacement".

I have friends who are economists, and I get in this argument with them all the time over beers.

There's economic optimization, and social optimization, and those are two different things that are often totally orthagonal.

Economic progress is often horrendously negative for people's lives and livelihoods. People don't just pick-up and move, or re-train in a completely different field with the fluidity that is often indicated, and disruption often destroys lives. This is why income inequality is getting really worrisome, and there's the huge debate over college education costs, and you see so many people now living in their cars because they're chronically under-employed. This is why Trump was pandering to Pennsylvania coal miners and the like. There are millions and millions of people kind of stuck and not sure how to move forward. Everybody in this country can't just be a fullstack web guy, and the alternatives are increasingly working for minimum wage at two jobs, each of which keeps you under 20 hours so they don't have to pay benefits.

That being said, you can't just put the brakes on progress so that people doing things that we don't need anymore are kept happy.

Ideally, we'd have mechanisms in place to help people transition, but we really don't. The best we have is things like the American Reinvestment and Recovery Act, various infrastructure programs (just big employment schemes), and affordable Community College vocational programs. The worst we have are predatory vocational programs that re-train people with useless skills, which are essentially scams to cash in on predatory student loans and GI Bill money.

This is the crux of the 2016 election, and although the virus has hijacked 2020 it probably would have been the crux of that one as well. You have Yang and Sanders proposing massive reforms, AOC with the Green New Deal, contrasted with Trump pushing a regressive approach, and everybody's polarized and yada yada.

Nobody has a good answer yet, or 300 million people wouldn't currently be arguing about it. Ideally we'd have a temporary system of 'engineered inefficiency' in the economy that would help people with legacy skills transition into new fields when employment dried up. But, nobody knows how to politically design, implement, or fund anything like that. So, what we have is this and it sucks.

I hope people smarter than me are working on this problem. I feel horrible about all the folks who have just gotten screwed, and have lost their homes, and are trapped in cycles of poverty. But, I mean, we are debating with strangers on the internet, so you know, no ill will towards anyone even if they disagree.

Re:Why hasn't prefab construction taken over? by seibelj on Monday October 12, 2020 @11:57PM (#24762119)
Very well put! And I agree that our retraining systems are horrendous. I’m probably not anywhere near as reasonable as you, as I can point to the government for every problem - why is college so expensive? Federally backed loans you can’t discharge in bankruptcy. Why do so many jobs need licenses that take years and tens of thousands of dollars to get when, for example, cutting hair is something you can learn on Youtube? Why does starting a billion dollar software company have way less friction and red tape than starting a convenience store? Why is housing so expensive? I can go all day.

Economic freedom leads to personal freedom and increased happiness. The never ending desire to have the government solve all our problems is what got us into this huge mess in the first place. I know that people are hurting, but the solution will emerge.

Re:Why hasn't prefab construction taken over? by phobosanomaly on Tuesday October 13, 2020 @12:09AM (#24762191)
So, yeah, I'm glad you're a free-market guy because I don't have enough free-market guys to drink beer and argue with. Although I'm not drinking beer (if you are, cheers), and we're not really arguing.

I am curious what the mechanism is from the free-market side to prevent increasing income inequality, and regulatory capture by corporations and the wealthy? If we de-regulate, what stops Bezos and Exxon, EvilCorp, and whoever from doing whatever they want (assume for a second that's not already happening to some extent under the current setup)? I guess that there's a market-based mechanism that is supposed to prevent that, but I don't know enough libertarians to have heard the argument.

I'm not convinced we should legislate our way out of anything either, but I can't get over the idea that deregulation = noone looking over the shoulders of those with absurd amounts of money and the wolf eats the whole damn henhouse.

I wish I had actionable ideas.

For a top 5 (or 7) wish list it would be along the line of:

- Outlaw billionaires the same way we’ve outlawed (at least on paper) monopolies. At that scale individuals have the power to sway governments. (A billion is likely not the right number, but it’s a good starting point.)

- Kill the money in politics. Make lobbying illegal.

- Kill the filibuster

- Kill the electoral college

- Decouple healthcare from employment (The only realistic solution I know of is socializing it).

- Provide a robust safety net (but get rid of the checks balances to prevent “abuse”). Just blanket give everyone $2000/month.

- Eliminate exemptions to providing benefits make it proportional to hours worked (worked an average of 10 hours a week for a month? That employer must provide 1 week of benefits to that person.) There is no common good from giving employer a massive expenses break to employ 2 people at 20 hours a week instead of just hiring one full time employee. This is gaming the system plain and simple.

I concede we need the state and am therefore not an anarcho-capitalist. My ideal state is as small as possible and no larger. Military and nuclear weapons are my biggest gotchas that I can’t reason my way around.

So you are asking me the wrong premise - if the state has no power, what regulation can a corporation capture?

I like corporations because businesses provide value. They can fail. The organizing principle has a straight-forwards goal of earning money. I don’t see any states failing (except for socialist ones like Venezuela) in a way that can put them out of business - they tend to grow forever in all directions, capturing more wealth and diminishing freedom.

The next question - do I care about inequality as a given? If everyone on earth had a healthy, purpose driven life but one family had 99.99% of all the wealth, would this be a problem? Basically do we dislike inequality because of envy or because most people genuinely have nothing?

You are correct that corporations are already running the show. Our biggest corporations are more powerful than most countries on earth. Because innovation in free societies is emergent and decentralized, the best the government can do is play whack-a-mole every few years as the free market laps them over and over.

I like the chaos, I like the unpredictability, I like weird people, I like having the freedom to do whatever I want. I want maximum freedom in all things and the least amount of coercion.

One area you should look at if you aren’t familiar is cryptocurrency. This is the most powerful innovation in regards to regaining individual freedom - financial freedom - that has come in centuries. The ability of governments to print their way out of debt is coming to an end, and individuals all over the world are going to have an escape valve from corrupt elites.

This was kind of a rambling response, no beer involved. Cheers

The problem with a state with no power is that it has no ability to prevent organizations from externalizing all of the costs of their profits. A simple place to see this is in environmental regulations. I can give plenty of examples, but before the rise of environmental regulation in the late 20th century, wide swathes of our country were regularly and freely polluted. We fixed lots of that through application of government power and imposed costs on polluters, both large and small.

Re:Why hasn't prefab construction taken over? by phobosanomaly on Tuesday October 13, 2020 @12:47AM (#24762362)
Ok, so this is kind of interesting because to increase freedom, we would have to actively reduce existing legislation. So both sides, the side that sees government as the problem, and the side that sees government as the solution, have to get legislators on-board to actually do something to implement their plan.

Oh man, things aren't looking good for any of us on either side.

Let's check back in 10 years.

Re:Why hasn't prefab construction taken over? by seibelj on Tuesday October 13, 2020 @01:13AM (#24762478)
I have a minority view well outside the mainstream. Libertarians do best on individual issues. When analyzed in isolation the libertarian argument wins out for many things.

While libertarians lack official power, the market is so powerful that it drives tons of human activity without people even being aware. Also, the belief that the government is all-powerful and can actually solve problems is 99% fiction. So while people look to the president as someone to blame for problems or praise for solutions, the truth is that very little of consequence is in the president’s (or government’s) control. So being a libertarian is a state of mind - the acknowledgment that the source of happiness and purpose is ultimately your own concern and no one else can do this for you. Not having a seat in government means nothing because libertarians generally don’t want government and it’s usually fairly easy to ignore, legally avoid paying taxes to through a variety of loopholes and structures in our Byzantine tax code, and is so ineffective it’s mind boggling that it ever gets anything done beyond corruption and graft.

So to come full circle, I believe governments are far weaker than most admit or recognize, and power is increasingly in the hands of private people and organizations. And I welcome this shift in power.

The concept assumes there are replacement jobs being created. That was true for a hundred years, it hasn't been for the last 20+.

At some point automation eliminates jobs wholesale, and there aren't replacements waiting. People always refer to cars replacing horses and point out that all those jobs surrounding horses were replaced with something else - manufacturing plant jobs, car salesman, etc. What they fail to mention is that HORSES were replaced with CARS - and we've got far, far, far fewer horses on the planet today because they're just not needed.

We're the horses...

Would you back a UBI-based approach to this problem?

Any cool moonshot ideas for how to approach it?

I disagree that’s what he’s insinuating. I take a much bleaker view of it. Those jobs are gone permanently and many of the new jobs we see on the lower skill end of the scale are ghost jobs that ONLY exist because it’s cheaper and quicker to just pay people to do those things than to automate them, but once the cost of development/automation has been paid for we’re going to see millions of low wage jobs disappear at a MUCH faster pace than we have to this point.

Job losses are only going to accelerate for the foreseeable future across most industries and they won’t be replaced by anything or at most a small fraction of what was lost.

Instead of the Jetsons (everyone’s jobs get simpler and simpler until they’re trivial, which seems to be what you’re leaning towards) we’ll have huge swaths of people that have so much time on their hands the time value of labor will drop to almost $0.

ATMs actually led to an increase in bank branches and employees, because while they did replace positions they made it cheaper to open branches; bank tellers can be used more profitably than just doing extremely routine deposit and withdrawals. If building becomes a lot less bottlenecked, the same may apply.

>> One big area where modular prefab can potentially make a difference is by reducing the need for skilled tradesmen, particularly electricians, plumbers and HVAC techs.

> To what end?

To the end that you can get your house built on a schedule that you want. A neighbour is a general contractor who has a good reputation: he, and the specialty teams he uses, are booked at least a year out.

This isn't too say we shouldn't train more skilled trades, but having a spectrum of of people available helps those you can't afford to pay top dollar for top talent to also get quality results.

It should also be noted that not everyone is gifted enough to be a top or even decent trade, yet we want as many people as possible to be productively employed. There will some percentage of the population that may be most productive simply following what the computer tells them to do:

No company exists to create jobs and nobody ought to wish any product particularly a vital resource like housing that everyone needs cost more in order to transfer money to the middle class workforce.

If you want to do that just be straightforward about it and directly raise that money via taxes and give it to families.

It will be increasingly obvious as increasing automation kills jobs that ultimately probably wont ever be fully replaced that we need a solution that isn't deliberate inefficiency to maintain jobs.

You’re comments come across to me as condescending, argumentative (without being productive), actively hostile to other users, and so one-sided you sound almost completely uninformed on the topic. All of which is unacceptable behavior on HN.

That said you’re not totally off the mark, but comments like “It astounds me that people on HN think that eliminating jobs without any thought to the social impact” is why you’re getting down voted.

How do you know now I or anyone else hasn’t given this thought? If you browse though old stories you’ll see tons of discussion on this topic.

My point of view on this is “It’s too late. The genie is out of the bottle and no amount of trying to avoid job losses is going to be productive.” Instead we need to work towards making our gross economic output support everyone. If basic necessities are all provided for (such as though UBI or some other idea) then no one will care if jobs are lost because then people can focus on figuring out how to productively use their time rather than worrying about finding a shitty, or even non-shitty, job so their family can eat and stay out of the weather. And without that we’ll continue hemorrhaging jobs until we reach a critical point where there will be an honest to god revolution in the USA and things will be violently reset (not corrected).
