There are two main reasons that individuals don't build their own houses and cars from scratch.

1) They don't know how.

Specialization is a thing. But this is a thing that applies to individuals rather than nations. You don't need every person to know how to mine ore or hang drywall as long as somebody does. But a country the size of the US could certainly contain someone who knows how to do any given thing.

2) They get paid more to do something else.

This is the argument that you get paid $200,000 to be a doctor and people who mine ore get paid $80,000 so it's better for you to do $2000 more work as a doctor and then pay someone $800 for ore than to put on a miner's hat yourself.

But this is again something that applies to individuals rather than countries. There are people in the US who already get paid less than $80,000, or less than $30,000, or even who are unemployed. It makes no sense to convert doctors into miners but it makes plenty of sense for the people who are currently doing something that pays even less.

So applying this to China and the USA - the USA has a median household income of ~$80k, and China, in terms of purchasing power parity, has a median household income of $32k. China has a workforce of ~775M people vs 163M people in the USA. The USA has ~7M unemployed people. For the USA to stop importing goods from China, we would need to 1) stop consuming those goods altogether (even if they're intermediate goods that go into things we do manufacture), or 2) employ US workers to make those goods instead of whatever they're currently doing (either employed or unemployed).

Employed Americans largely earn a lot more than employed chinese people, and there just aren't very many unemployed Americans. Based on the value of imports to the US from China vs Chinese GDP($440B vs $17.8T), we import about 2.5% of their output, or the equivalent of ~20M people's output if we naively scale. I don't think there is any way around the fact that significantly reducing imports from other countries means we significantly reduce our consumption in absolute terms (i.e. we have a poorer standard of living), just out of spite for other countries.

> the equivalent of ~20M people's output if we naively scale

Or about 12% of the US labor force. Meanwhile the 12th percentile US income is ~$22,000, i.e. less than the $32k median in China, and half of the jobs there are above that median.

Obviously these numbers are all useless napkin math and none of it really works like that, but the premise isn't inherently absurd. If China is subsidizing manufacturing in order to capture manufacturing jobs and those jobs pay more than what many in the lowest quartile of the US are currently making, there are people who could be made better off by having those jobs back, and they'd still only be paid about what we're currently paying to China.

And this before considering the general arguments about advantages to proximity of manufacturing, e.g. being able to talk to the people in the factory in your timezone in your language assists in product development so the location of the factory has an easier time developing new products. Which allows not just the manufacturing jobs but the whole rest of the company to be there, instead of those jobs starting to get eroded going forward.

The US manufactures more than ever, and the % of GDP in manufacturing has been flat for 70+ years now. The jobs didn’t leave, so they’re never coming back. They got automated. Just like we need vastly less farmers than in 1900 to farm more than ever, we need vastly manufacturing jobs to manufacture more than ever.
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by AnthonyMouse on Tuesday April 08, 2025 @09:11PM (#43627989)
Automation increases production efficiency. Jevon's paradox says this will generally increase consumption, and in fact it has, so US consumption has gone up but production is flat. The difference comes from increasing imports from manufacturing in China. If the US manufactured the additional stuff instead of importing it, it would have more manufacturing jobs than it does now.

At what wages? Come on, man. Do you know what the average wage is in China on an iPhone assembly line? The pressures on workers?
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by AnthonyMouse on Friday April 11, 2025 @02:00PM (#43656599)
This is why the US needs automation. You don't want jobs assembling iPhones by hand, you want jobs building and maintaining factory automation equipment. But this is the trend globally anyway because a) it's becoming increasingly possible and b) the wages in countries like China have been increasing, so there is less "cheap labor" available in the alternative. But if you have an automated factory that requires trained workers making middle class money instead of a sweatshop, then why would the US want it in China instead of at home?
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by SideQuark on Friday April 11, 2025 @09:26PM (#43660481)
Decent paying manufacturing jobs are never returning; they’re automated out now.

It’s like wishing all of America would return to farming jobs, which once employed the majority of people. Then farming got automated such that now only a few percent of workers produce vastly more than those ancient hordes.

That’s where manufacturing went, and the rest of the world is as surely automating out those jobs too.

More of what, exactly? I looked at steel production data (in metric tonnes, not dollar value), US production has been flat or slightly declining since 1970.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by Spooky23 on Tuesday April 08, 2025 @11:16PM (#43628580)
Computer components, medical equipment, vehicles, aircraft, chemicals, etc.

Steel is something where value matters. US steel is usually higher grade or recycled with more value. Korea churns out tons and tons of low value low margin rebar.

You bring back manufacturing by investing in clustered industries. New York has a bunch of semiconductors. There’s a ton of chemical industries around Philly and Houston.

The iPhone is made in China because they have the best manufacturing for precision products. If you want that here, you have to invest.

People normally show a slowly increasing graph to claim that the US manufactures more than ever- but it's primarily because of hedonic adjustments for Intel chips. If you take that out it falls off a cliff in the 2000s during the China Shock.

Back of the napkin, we could spend 3% of the federal budget to pay each of those 20 million people an extra $10k a year, and avoid destroying some 10% of the global economy. If we wanted to do that, I guess.
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by aj7 on Wednesday April 09, 2025 @03:15AM (#43629625)
No one will hire the people you are describing. We had 3.5% unemployment, before Trump began destroying the world economy. People in most fast food restaurants are making $30k. In fact the “entry level workers” and “illegals” were relatively happy. It’s the middle class workers who vary between desperate and enraged, because $45-$65k does not approximate the expectations raised in their childhood. What I’m saying is vastly oversimplified, but you get my drift. There is tremendous housing shortage, due to government policies that surreptitiously favored rising prices for incumbent homeowners, and corporate speculators. Healthcare is apportioned according to education level. Food is remarkably expensive.
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by AngryData on Wednesday April 09, 2025 @05:49AM (#43630459)
Maybe where you live people making under $30K for even the lowest entry level job is exceedingly rare, but there are still ass tons of people earning below that, especially in rural areas. Half of US states have a median wage under $40K, that leaves a LOT of room for jobs paying below $30K. And no those people are not happy, yeah housing is cheaper, but goods and services are not. Amazon doesn't charge you less for living in Mississippi instead of New York. Many stores that do still exist farther out have higher shelf markups too except for the highest demand bulk products where competition actually exists.

Specialization also applies to nations. It is literally the foundation on which David Ricardo described the comparative advantage economic model.

We can argue some nations have been pretty unfair with their tariff rates over the years, but let’s not ignore 200 years of economic science.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by AnthonyMouse on Tuesday April 08, 2025 @08:39PM (#43627839)
That applies when your model of a country is on the scale of something like Switzerland or Ireland, which is to say something on the scale of Pennsylvania or Colorado.

The US is more on the scale of a continent than a country.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by WillPostForFood on Tuesday April 08, 2025 @09:34PM (#43628100)
Economics isn't science, and while Ricardo has some brilliant insights, it isn't a science; he barely models anything. It isn't even a hypothesis since you can never really test it. The core of his idea is this:

the rate of profits can never be increased but by a fall in wages [...] If, therefore, by the extension of foreign trade, or by improvements in machinery, the food and necessaries of the labourer can be brought to market at a reduced price, profits will rise.

I.e., use trade to get to lower wages

When you scale up the thinking past rudimentaries like 'hanging drywall', it still applies to nations - instead of "do we have enough people who know how to mine ore" it's "do we have the capability of mining enough ore to meet our needs" and the various intricacies that come with those massive-scale problems - problems that are much more easily solved when backed by a global economy.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by AnthonyMouse on Tuesday April 08, 2025 @08:47PM (#43627880)
That's something different than specialization.

Suppose you have enough mining production to meet half of domestic demand. Then you still have mining production, and know how to do it, and if it was necessary you could scale it up or reduce domestic consumption somewhat from the uses that aren't as important. Whereas if you outsource all of it or nearly so, i.e. actual specialization, it's a vulnerability whether to enemy action or just a single point of failure that subjects the whole world to unexpected localized turmoil in the only place that makes that.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by bluGill on Tuesday April 08, 2025 @09:24PM (#43628055)
You missed one: the person they can pay is better. I have rebuilt engines, but my cars go a mechanic because it is done in a day not a month. I can texture drywall but I need a lot more practice before it looks even like it should. I know 'scabs' who did a job while the union was on strike - the union people were 10x faster for similer quality - give a few months and they would be that fast. (The strike didn't last that long)
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by oceanplexian on Wednesday April 09, 2025 @02:06AM (#43629336)
It’s interesting you brought up scabs because other than a local service economy, the entire concept of a union can’t exist in a globalized economy. Companies will simply pay labor overseas in countries where organized labor is illegal.
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by bluGill on Wednesday April 09, 2025 @06:49AM (#43630744)
Unions so long as they don't demand too much (normally money but could be other factors) can exist just fine. Experience is valuable as is having the factory close to the engineers. Local shipping helps. Automation means there are not many in the factory as well so you can pay more.
Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by mmooss on Tuesday April 08, 2025 @11:33PM (#43628660)
It's a revolutionary economic argument that specialization doesn't apply to countries, and you omitted organized groups of individuals called 'companies'. Economic structures are far larger and deeper than individuals (or companies).

> a country the size of the US could certainly contain someone who knows how to do any given thing.

Ore may be much cheaper to mine in another country - maybe because of geology or weather or because they have a great tradition of mining including more local skills, or because their economy is better structured for it - financiers with expertise in financing it, laws and regulations that are better designed (because of greater local knowledge).

Those things actually happen.

And don't think such specializations are transferrable; nobody really succeeds in doing that - just try changing one company's culture. Why haven't other Silicon Valleys and Apple Computers been developed, despite so many efforts?

What is the sense of wasting resources on things the country doesn't do well, so some nationalists can ... do what?

> It's a revolutionary economic argument that specialization doesn't apply to countries

It isn't. The point of specialization is that people can become experts in things, so that not everyone has to be able to do everything. But the goal explicitly isn't for there to be only one person or only one company that knows how to do something -- that's a monopoly, and it's very bad. And if there are going to be a dozen companies that know how to do something (rather than needing every individual at every company to know how to do it), at least one of those companies can be in the US.

> Ore may be much cheaper to mine in another country

Ore isn't really specialization at all, it's resource availability. You simply cannot mine something in a country that doesn't have any. But the US is big enough to have almost everything and even to the extent that it doesn't, it can a) sell mining equipment to those countries that have it and b) ensure that it's more than one country acting as a supplier of those things, instead of allowing a dependency to form on a single one.

> Why haven't other Silicon Valleys and Apple Computers been developed, despite so many efforts?

Apple is an abnormal edge case because in the middle of their existence there was a monopolist (Microsoft) excluding all other competitors while keeping Apple around in an attempt to fend off antitrust scrutiny for their unlawful practices. That allowed Apple to a) invest in designing high quality products while Microsoft was stamping out any other competitors and b) build a strong brand (because the alternative was Microsoft).

To replicate that in other circumstances you have a chicken and egg problem, because you need the scale to have the resources to design high quality products and build a strong brand, but you don't have those resources or that brand with which to achieve that scale. The only ones who do are the other large behemoths, but large incumbent bureaucracies tend to become mismanaged and there aren't actually that many of them.

You also don't want others to replicate Apple, because Apple is a vertically integrated conglomerate. Everyone keeps trying to because they see Apple making a lot of money, but what they should be doing is playing "your margin is my opportunity" and establishing a competitive market where devices are made of fungible components using open standards, because that's how you defeat Apple instead of becoming Apple. It's no coincidence that PCs still have more desktop market share than Android has mobile market share, because the PC platform is still more open than mobile and to the extent that Microsoft has been losing market share it's because they're increasingly trying to lock down the platform and abuse their customers. If you have two closed platforms, the one with more resources is going to win, because then it's Apple vs. just you and Apple is bigger. But if you have an open platform, then it's Apple vs. everyone and everyone is bigger.

> What is the sense of wasting resources on things the country doesn't do well, so some nationalists can ... do what?

Not be dependent on a single supplier for 80-100% of the global production of some important product.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by mmooss on Saturday April 12, 2025 @12:42AM (#43661416)
It is revolutionary to say specialization doesn't apply to countries, no matter how many times someone on HN says it. Removing competitors in other countries doesn't add competition to the market.

> Ore isn't really specialization at all, it's resource availability.

You just made that up. What is it based on? Also, resource availability is definitely part of specialization - countries specialize in what they can do more efficiently than other places, which depends partly on resource availability. It also depends on infrastructure, capital, laws, regulations, skills, labor, and many other variables.

People haven't copied Apple and SV because it's very hard to do it. Nobody does it with any successful company. You just can't copy those things.

> Not be dependent on a single supplier

Again, by reducing suppliers - and essentially worldwide in this case - you reduce competition. Now the public subsidizes a local supplier who is not good enough to compete, and therefore the public also gets a substandard product with little hope of competition arising.

> hang drywall

I can frame, but I'm a disaster at hanging drywall. I finally hired a craftsman to do it, and zip slap bang he had hung it and it was straight and the joints were tight and even and I could hardly believe it.

Re:The Decline of the U.S. Machine-Tool Industry and Prospec... by aj7 on Wednesday April 09, 2025 @03:02AM (#43629543)
Nobody is concerned with any of that. A $15,000 Chinese mechanical engineer is just as productive as an American who expects $70,000 for his efforts. This repeats over and over, from the lowest level workers to the executives. It is destroying the lives of our non-elite workers, who in turn, voted for a mad man. It’s only going to get worse. The hunger for knowledge and development is much stronger outside the U.S. than inside.

Tariffs are going to put our high tech industries under enormous pressure. There are two reasons. It makes sense to import parts and lower tech components of everything we manufacture because our trading partners have developed an economic advantage in the production of those types of parts. If we make materials and those lower tech factors of production more expensive, we kill ourselves. It’s economic suicide. And high tech industries live by exporting. In equilibrium, the market outside the U.S. is much larger than the internal market. As we are to China and the rest of the world, as Germany, roughly, is to us, we will prosper only by exporting high tech, advanced design products. Everything we do has to cultivate that process.

It applies to countries too. It’s the core argument of comparative advantage, and it’s been mainstream economic theory for over 200 years. Your argument is incomplete because you’re not considering the wages paid in other countries, and crucially, the exchange rate.
