Texas has far less population than California. If you adjust they perform about the same. Oh, perhaps you should look at GDP per capita, where California isn't at all extraordinary. Hmm, it's almost as if you should compare properly?
Imagine bowing down to a state and ignoring facts. I never said California wasn't performing well. But in a pro-business country (far more than France), one of its biggest states, with its largest population, that is bigger than most countries on earth, why is it so shocking that their GDP is that high?
