Silicon Valley used to be a place with cheap land where people went because the cost of living was low, and they could tinker with cool ideas whereas, in the expensive East Coast cities, they'd have to work themselves to death just to tread water. California was this place where you could come and do cool stuff and build on land the East Coast elite didn't want. It's no longer cheap to live there. Tinkering with new…
It's no longer cheap to live there. Tinkering with new ideas on some modest amount of savings and "odd jobs" or consulting is no longer possible. Expensive real estate leads to calcification and risk-aversion and cultural death. It's why urban ecosystems (including VC-istan, which is not a city per se) turn into hellholes shortly after their peak of greatness. Many of the world's top cities are expensive as all hell,…

In the long run, this will even out as housing is built-- it's just slower to build new houses than create new jobs or reasons for people to live somewhere.

The dumbshits who cheer on high real estate prices think it's a demand improvement, when it's almost always (over 95%) a supply problem, that causes real estate to go up.
The most expensive city in the country is Luanda. Next is Moscow. Neither is known for a robust, healthy economy.
People tend to mistake the second for the first and assume that expensive real estate is a sign of something good. It's not, and the long-term effects of expensive real estate are extremely undesirable.
