The housing crisis won’t be properly solved until the job site crisis is solved with it. There’s a whole lotta land suitable for housing, but most of those parcels lack modern, stem jobs. Until that’s solved, via remote or satellite work, the jobs will be where housing is expensive, and the lesser cost housing will be the province of retirees or the tech-poor.
100% correct. Building more in the same locations is simply not feasible physically, economically or considering infrastructure and services. There's plenty of space but we seemingly have no appetite to consider decentralisation, even if all the tools are now in place to make it work.
Of course the jobs are located where housing is expensive: the housing is expensive because that's where the jobs are.
There's a whole lotta land suitable for housing in the places where those jobs are, too, but most of it is locked up in restrictive zoning which prohibits development at a sufficient density to keep up with demand.
