and few companies are willing to build any more

I don’t think this is actually true. At least in my area, developers would LOVE to build condos and apartments all over the place, but local laws are holding them back.

I suppose even in a perfectly willing area that upgrades its infrastructure to support more people, you don’t want to move people in too quickly, before that infrastructure is available. But it’s easy to see that become a self fulfilling prophecy: we don’t take immigrants because we don’t have the infrastructure, and we don’t build the infrastructure because there’s no demand for it.
