Yes, it's seriously unhealthy to have most of peoples individual wealth tied up in the fact that there's constrained property supply. If we just built a bunch more housing (or removed net immigration) such that house prices dropped say 25% (which would still be too little, actually), people would be in negative equity, the banks would collapse, government voted out, riots in the street. Yet it's whats needed. If a late 20's professional in London is earning £40,000 after tax they're doing fairly well, yet a one bed flat in zone 2 would still be 10X their annual income.
