Agreed. Thankfully we know what it takes to make housing a crappy investment vehicle. Build more housing. Build so much housing that returns on capital invested are flat, live Tokyo since 2000, or negative, like Seattle over the last five years.
Make building housing legal again.
Also. Renters deserve housing too. Restricting housing to the owner occupied is a great way to hate things by social class but I see no reason to further favour a population that’s richer and more powerful than the rest of the population already.
