I have heard that "everyone" would move to
* San Francisco
* Bend, Oregon
* Boulder, Colorado
* Seattle
* Austin, Texas
* New York City
* Santa Barbara, California
* Hawaii
* Montana
* and on and on and on
You know what? No, not everyone is going to move to New York or Bend or San Francisco. Building more housing keeps rents in check. And if some more people get to live in a place they want to be, that is a good thing.
