> definitely blame tech for loading an entire industry into a metro area
Supply and demand gonna supply and demand. It's weird to "blame tech" for existing and injecting a massive amount of jobs into our economy; there's no metro region that could have handled that growth without the same effect on price, and there is no singular entity responsible for concentrating tech into a single city instead of distributed more evenly.
Maybe Houston could have come close to handling it without massive price increases, but I'm guessing Houston is too spread out to enjoy strong network effects, and probably would have become gridlocked with traffic to boot.
New York could have "handled" it, from a raw housing & transit perspective, but the region is already pricy and all of Manhattan (which has the best access to jobs and transit across the metropolitan region) has long since gentrified, so I don't know if that really counts.
(Of course, part of the reason no region could have handled it is precisely because of how Americans approach zoning and growth. Like our politics, our cities and neighborhoods seem to be static until there's an absolutely overwhelming force against the status quo, and even then sometimes that's not enough to change anything)
