There are still some southern states that have massive poverty. The union did not serve them well. I can see how they would be better off on their own. Hawaii as well. And its not just about poverty. Hawaiians would like to regain control over their culture, tourism levels, and so on. King of your castle. Even if your castle is just a shack. Counts for a lot. Also cities like Chicago and Detroit experienced huge declines, because of trade with China, that mostly benefits California. I can see how they would like their own policies on trade.
