The parent doesn’t seem like they’re renting land though. It seem like they are renting houses which doesn’t suffer from the problems of ground rent because there’s actual service being provided.
We should increase supply. Oh, and wealth tax for rising inequality too.
For what it’s worth, I took abandoned or ruined houses in desirable areas, bought them cheap, and spent my own (and my wife’s) time and labour renovating and furnishing them. I created housing stock from mouldy rubble.
Also, please note, I did not invent capitalism. I would much rather everybody could live like this.
"Stop restricting the housing supply, and don't prop up house prices by buying mortgage bonds" I shout to noone in particular.
