I think that plan will backfire. Look at Detroit.

Secondly, everyone will draw different conclusions when looking at the same data.

I don't think San Francisco will ever be Detroit. The geography constrained SF from physically expanding to the point where it can't sustain itself, unlike Detroit.

I think more likely is hitting some low point, and then a crackdown/reversal of the politics. I think a more apt analogy is SF now is like NYC in the 80s, and the 90s cleanup is coming sooner or later.

If strip clubs and peep shows replace all these empty retail fronts we’ll get there.

Sounds like open liquor laws will be a go post covid. Party time.

Isn’t SF zoning and city laws much more NIMBY and less objectively progressive than the cities reputation?

I thought that’s why it’s so dirty and full of obvious problems like petty crime and homelessness. A local political system disconnected from solving the IRL problems.

You’re right though. The solution to SF is actual liberalism of laws around the fun stuff and help for those in need to get them out of the cycle of criminality by being more reasonable with them (shelters and safe injection sites with opiate programs so they don’t have to steal and destroy i property in order to live).

I could see the latter happening like it is here in Canada (there’s always that homeless/career criminal niche everywhere) although it seems like 10x higher out on the west coast and given the tax rate as it is already super high idk if they have the appetite to do the right thing and cut other useless stuff to offset it.

For better or for worse, accurate or inaccurate, there were two lessons pretty universally drawn from Detroit: (1) White flight is very, very bad news, and (2) Heavy unionization makes factories uncompetitive.

Especially (2) -- again, I'm not saying whether this is the right or wrong conclusion -- weighs heavily on the states that picked up auto manufacturing that fled Detroit. Obviously there are contrarian takes, but these have very wide mindshare, and I don't think it's true that "everyone will draw different conclusions".

I'm not sure factories closing down in the Bay Area is a big issue as there aren't a lot. The bigger issue is upper middle class and upper class people and their taxes leaving. On the other hand, the area generally (if not necessarily just SF proper) has a lot of attractions that Detroit never had. So it's reasonable to assume that housing prices could drop to a more sustainable level. Of course, one implication is that municipalities would probably have to operate on lower budgets than they do today.

In general, SF and Bay Area are not necessarily the same story. Plenty may choose to live in South Bay especially if prices drop but not in the city.

As a Detroiter I'm curios to hear why you think Detroit went the way it did.

Over-dependency on a single industry, unwillingness to diversify, and an arrogant assumption that the same work could never be done elsewhere. Add in highways, commuting, and an infrastructure maintenance death spiral as domestic car production lost its major advantages. Rising crime added to the death spiral, as people who could moved out and the general deprivation of Detroit grew.

Many of the suburbs developed their own economies, which further encouraged people to move there instead of Detroit proper.

Lots of racism played its part in various ways. Lots of room to debate the precise degree, though the debate is probably not helpful at this point.

These days the high taxes (property and income) and auto insurance rates are big problems.

Only a few of these really apply to SF. Though the arrogance of assuming the good times will roll on forever seems accurate.

"Over-dependency on a single industry, unwillingness to diversify, and an arrogant assumption that the same work could never be done elsewhere."

Like San Francisco?

Only to the extent that San Francisco is over-dependent on tourism. "Tech" is both not really a single industry in the way that auto mfg is and far less dominant than one might guess.

Though if you can convince me that Salesforce and Autodesk are meaningfully in the same industry as Spring and LendingClub, I'm all ears.

There seems to be an awful lot of overlap between the positions they are looking for in San Francisco:

Autodesk: https://autodesk.wd1.myworkdayjobs.com/Ext/2/refreshFacet/31...

VMWare (which owns Spring): https://careers.vmware.com/main/jobs?page=1&country=USA&stat...

LendingClub: https://lendingclub.wd1.myworkdayjobs.com/External/0/refresh...

Sr. Release Engineer/Build Engineer, Director of Data Initiatives, Sr Staff Engineer Cloud/Saas Security, Sr Product Designer...

If everyone is doing web/mobile development and they suddenly realize that web/mobile development doesn't need to be done in a 2-square-mile area...

You're absolutely right! The companies I mentioned do hire many people with similar skills.

Do you think it's possible that this might not be quite the same as being in the same market and thus being a direct commercial competitor for a company's offerings? Otherwise every company is in the Human Resources and Accounting industries. Perhaps the companies in question are not in commercial competition with one another, and only competing for a certain set of skilled technicians? Do you think the point imtringued made about downstream suppliers might be relevant?

Again, you're completely right. There genuinely is a lot of overlap in titles and skills sought! It just might perhaps be possible that this is not quite the same as all companies concerned being in the same industry. Or perhaps I am wildly wrong! Can you help me with where I might have erred?

The question of how one chooses to define an industry quite aside, the degree to which San Francisco's employment depends on "tech" is easy to overstate. Based on news and this website, you would think it was a third to a half of SF jobs. While an easy and completely understandable conclusion to draw, this would be a dramatic overstatement.

Detroit's problem was not that the companies there were direct competitors, it was that all of them were producing automobiles. When American automobile production moved elsewhere and took a large number of well-paying jobs with it, the bottom fell out of the city's economy.

What do you expect to happen to San Francisco if it loses its "tech mecca" status? Will the financial sector or the tourism sector supply enough high-paying jobs to make up the difference, or will the money drying up cascade down through the service industries?

I can see I have been unclear.

Detroit's problem was that automotive production was and is a single sector. This is not true of "tech", as shown by a random sampling of companies being in wildly different economic sectors.

I hope this is better! Thank you for the chance to improve my communications skills. Have a nice day.

> I hope this is better! Thank you for the chance to improve my communications skills. Have a nice day.

Unrelated, but I've always found it interesting how people try to avoid appearing like they're actually invested in the conversation they're having and the effect the results have on them.

"I'm not here to exchange ideas and make my understanding of the world better, no, I'm just here to improve my communication skills and I want you to know that!"

I understand the need for self-preservation, but going to this length of lying to yourself and observers to defend your ego is amusing in my opinion.

I use it to place the blame of someone refusing or failing to understand on myself. The goal is not to signal a lack of investment, but to give someone a way to admit to being wrong without actually having to admit to anything. It sometimes helps remove a person's ego as an obstacle.

It's the difference between "I failed to be understandable" and "You failed to understand". With the former, they can come back and say that since I've clarified so helpfully, they agree with me without impugning their previous position. The latter allows no such latitude.

> but to give someone a way to admit to being wrong without actually having to admit to anything

It also shows that you have no humility and can't accept that you might be wrong. That's what I'm trying to say.

> It's the difference between "I failed to be understandable" and "You failed to understand".

You can't even imagine a situation where the other party in the discussion understands your perspective but simply disagrees?

> It sometimes helps remove a person's ego as an obstacle.

Start with yourself.

As an aside, I understand your argument. I simply disagree.

Tech is not a single sector, but it is a single method of doing things. In the same sense that factories exist in more than a single sector, but it largely disappeared at the same time with offshoring.

If, hypothetically, all the issues with having development teams cheap parts of the world went away, that would impact almost all of tech. It hasn't happened yet, but I wouldn't rule out the possibility.

Honestly, that would be amazing. It would enable a golden age of technological development. I think it's just a bit more far-fetched a near-term future than a single economic sector leaving a particular area, and not really directly comparable to Detroit's story.

Car manufacturing needs lots of downstream suppliers that usually have expertise in nothing but automotive parts. The end result is cars and nothing else.

You can build tech for car manufacturers, you can build tech for taxi companies, you can build tech for restaurants, you can build tech for any industry.

San Francisco is still a major financial hub by the way.

According to this talk [0] the reason is that the newly established car industry encouraged a massively unsustainable development pattern that eventually led to the bankruptcy of the city and since its the first city to be built with this pattern it was also the first to fail. Lots of other cities are suffering the same fate. New low density development at the edge of town at the expense of the self sustaining downtown core and then at some point the maintenance costs exceed the tax income and you get a city wide decline.

That's a very optimistic point of view on the ability of people to learn from examples. No matter how hard SF fails, there will be lots of people going around and telling how it have failed because of not building enough social housing for the poor, not having high enough taxes, and allowing rich to escape after robbing the city dry. Just like there are people saying that communist countries fail because of US sanctions.
