The "Housing Theory of Everything" argues that restrictive housing policies in prosperous cities have cascading negative effects across society. By artificially limiting housing supply through zoning and other regulations, these cities drive up housing costs, exacerbating inequality and hindering economic growth. This impacts everything from family formation and geographic mobility to innovation and political polarization. High housing costs force people to live further from job centers, increasing commute times and contributing to climate change. The theory posits that reforming housing policy to allow for significantly more density would unlock a range of societal benefits, fostering greater dynamism, affordability, and opportunity.
Hacker News users generally agreed with the premise of the linked article, that housing shortages significantly impact various societal issues. Several commenters shared personal anecdotes about the difficulties of finding affordable housing and its cascading effects on their lives.
