The policy solution is known -- ease restrictions on increasing the housing supply.

If you're asking how to get that passed, well, that's an education problem. You need people to understand why rent control is not a solution so that they are not willing to accept it over something that actually works.

What I’m getting at is that’s policy and doing are inextricably linked and frankly people have had enough of sneering technocrats telling them the optimal solution that they’re powerless to peruse. Rent control is a bad idea... but sometimes the only way to bring good ideas in to the realms of possibility is to do bad ideas first.
