American?
Bull$hit. I'm an American, and I don't think like that, nor do most of us. And it doesn't require being socialist or Marxist to "love thy neighbor".
Having lived and worked in the silicon valley, along with having family members in some of these mobile home (not "trailer") parks, there are very few places for the (mostly elderly) residents to move to.
Managed care facilities run in the THOUSANDS of dollars per month, and most of the other mobile home parks in the area are full, many with waiting lists.
No, the problem is like most of the other problems in Kalifornistan - the few pockets of prosperity are no longer affordable for the folks (and their parents) who made it so.
