That sounds specifically like the housing shortage that is afflicting some of the most dynamic, productive parts of the country, like NYC and the California Bay Area. Driven by NIMBYism and some other things, those areas stopped building anything like enough housing, with the obvious result that demand outstripped supply and prices rose, putting them out of reach of many. That's kind of the origin story of the YIMBY movement, which started forming to fight that trend.
