Its wild how the solution to housing costs is really just: Build more housing. Keep law and order. No it doesn’t need to be “affordable”. Yes rent control is a terrible idea. Just build more housing. Note: that the US already has plenty of housing and housing costs basically go up in areas of low crime relative to economic opportunity. If you build housing, but allow crime to rise, you have wasted everybody’s time.
So yes, it really is "just build more housing." The problem is: why would you build more housing as prices fall?
