Housing in the Netherlands is really awful, in the '90 the boomers have build smaller apartments for their parents to move in and actually profit in an illicit way 2x of their real estate gains of sometimes 6x. No boomer is living smaller to make room for the next generation. I think the best way to combat current shortage in housing is putting up a limit on m2 that an individual could claim. 300m2 for a single person in a metro area while being on a pension is not sustainable in current conditions.
