Society needs to start by agreeing that banning for-profit land-lorder is a moral imperative. Then we figure out how to eliminate the rentier class without everyone else not getting hurt. Luckily, there are options:

2. Hard stop it, and immediately declare a long-overdue debt jubilee or write-down.
