Economically, California is (at least was, I don’t know if it still is) capable of sustaining itself separated from federal money. It even has the power to set national standards, like the “known to cause cancer” warning. Which may seem like it’s slapped on everything, but from what I remember, its slapped on everything containing any carcinogens, covering products even after their lifespan into disposal (if you burn a product but it doesn’t destroy the carcinogen it’s still a risk since it’s airborne or in waste.)
Alabama is just completely fucked if they get cutoff from federal money.
