This is also the cause of the gentrification anger and resulting NIMBYism. If you build some, but not enough vs what's actually needed, you get both: - expensive new market-rate construction that most people can't afford - localized bumps in rent for increased relative desirability - overall prices that continue to rise across the city because the new construction was just a drop in the bucket compared to the need And then it's easy to point to "they built that building AND our rent went up!" as a reason to oppose construction, even though in the long run they'd go up even more if that building wasn't built.
