It’s not the parties that are the issue, it’s the people.

If we want affordable housing, we need to absolutely tank home values, by as much as 80-90% in some markets.

Most people simply won’t vote for a party or a policy that does that, because most people (and especially most voters) own their home and aren’t willing to give away literally hundreds of thousands (or in some case millions) of dollars even if it helps other people.
