What you are describing are diverse cities, not california as a whole. NY is even more diverse than than california if you just pick a diverse city and extrapolate that to the entire state. If you want global, it doesn't get any more global than NYC. Not sure why you are pretending california or LA is special. The only thing california has going for it is great weather and constant flow of chinese money and a tech bubble propping it up. The east coast has pockets of diverse cities and suburbs as well. No different than california.
