That's too dismissive of a problem that directly affects maybe 20 million people. There are 10 million living in LA county alone. They're not just gonna "shrink back." Whether they move out or stay put, they're gonna do something, and chances are you are not going to like it.
This reminded me of the time my 4 year old son was in a serious car crash. When I asked him what happened, he described how the entire right side of the car was violently destroyed. When I asked if he was afraid, he said "No. I was sitting in the other side of the car." Sometimes problems stay where they begin, but usually the consequences spread all over the place.
