Every US politician in my lifetime has had the brain disease of believing that you build wealth by owning a home, even though this belief is fundamentally incompatible with affordable housing. We have to break this belief, somehow.
It's the other way around. Every homeowner wants the value of their home to appreciate and the politicians they choose to elect uphold these values. Politicians listen to these homeowners over renters because turnout and political contributions are both substantially higher among homeowners.
