I think another key factor to happiness in California is the weather. It's hard to find a place in Europe that is top-tier economically and has nice weather year-round. No matter how good life is in other respects, it's tough for some people (myself included) to feel good when the weather is cold, gray, rainy, and dreary for months on end.
