Does California take any federal money? Do any of those plains states provide food to California. I don't think you would like this game as much as you think.
Does California get its food for free from the plains states? No? Well then, you can sit down and STFU. BTW, over half of the produce in US grocery stores comes from California. Also, over 90% of the goods coming into the US from East Asia comes through California ports. No California, no Walmart.
How do you like them apples?
