Probably because all the younger people, who are not on welfare, are leaving the state to raise their children in an AMERICAN evironment that has an AMERICAN future....
Younger people are leaving California in order to be able to
afford to have children. It used to be somewhat affordable to live in California because you could depend on the value of your house going up year after year. You could take out a home equity loan to pay your mortgage.
No longer. If you live in California, you'll probably have to visit your grandchildren in another state.
