People respond to this agglomeration factor with the argument we should “hire remote cuz the internet thing”. But the other factor to consider is how we are less tied by our jobs to physical location and that allows more choice in where people decide to live too. A lot of people want to live in the Bay Area and other coastal cities. They don’t want to live where housing is cheap in the Midwest.

So you may have a liberating force in the way jobs have changed, but that works both ways.

People are moving to the big coastal cities. The big coastal cities (and states) are doing a piss poor job of accommodating this - actually they’ve taken active measures to worsen the housing problem with zoning and tax rules.

I would guess that google would get a lot more bang for its buck if it just outright bribed politicians with that $1 billion to enact policies that allowed constructing of more housing and better transit.
