I remember reading some history of England, and at one point a lot of the land was not owned by individuals and the people that owned the land could and did raise the rents to an unreasonable extent. The article said high rental prices were bad for the economy because money was being spent on a non-productive item (rents) and not available to be spent on productivity related items (goods and services).This should not be allowed to happen. And it does. Like I said, I give up. What's to happen to people?
At some point it got so bad that it galvanized change and somehow or other the land got removed from the big land owners/monopolizers. I would guess via taxes but maybe not, I am totally blank on how the history went at that point.
