I think it rather obtuse to make generalizations about California and where the kids go to school. I would venture a guess there is as much prejudice toward California as the reverse.
I come from a rather large family, born and raised in NY. We now live in the four corners of the country, all in states connected to an ocean. We can’t picture ourselves living in a part of the country that is landlocked. People want to be in places they find the most comfortable. Sometimes this means a liberal or conservative atmosphere and sometimes it is really only means they like the weather, the terrain and the activities available. How silly to point fingers indiscriminately.
