In the UK, property developers are forced by the govt to build a certain proportion of social housing into their developments, or to subsidise the building of social housing elsewhere. Obviously, this means the high end property is less desirable (because big spenders are forced to live next-door to social housing tenants). And the social housing built will be boxy and low standard, so again, less desirable, and unprofitable for the developer.

Whenever the govt distorts free markets, it creates shortages. And housing is one of those markets where we REALLY need the private sector to be allowed to build properties that will meet true market demands, rather than properties that will satisfy govt ideologies.

If housebuilding was unconstrained, there would be more of it, which would be good for people at both ends of the market. More high end property means lower prices at the high end, more people moving up out of mid-scale housing, and so on. Prices would fall across the board, and eventually no one would need social housing. We’d ALL benefit.
