And the same politicians that those homeowners vote for. And lobby. Especially retirees who have time to do things like endlessly harangue their local councils to implement NIMBYist policies to prevent increasing housing supply in order to drive their housing prices higher. Of course, couched in language like "preserving the historical character of the neighborhood" and "keeping the riff raff out".
