It’s not hard to come up with solutions that seem likely to work (build a ton of new housing, tax unoccupied housing, etc). It’s hard to come up with solutions that seem likely to work and will be selected democratically by the voting populace.

This is true in general; it’s completely obvious how to end the COVID pandemic and stop global warming (universal vaccination and massive reduction in burning fossil fuels, respectively). But people will just not choose these obvious options.

If you can figure out why, and how to change that, you’ll have an incredible life ahead of you in politics.
