I've recently been thinking a lot about policy changes that might help with housing affordability, and the same thing keeps happening: every time I think I've come up with something clever, I eventually realize that I've just accidentally made things even better for people that started off with a lot of capital.
It feels like aside from explicit redistribution of wealth (raise minimum wage, tax high income earners more, raise high-end property taxes), you can't change _anything_ without making the rich richer and the poor poorer.
