Yes, IF the rightist seceding states simply cut off all welfare and other such support the city people count on instantly. I think we'd have to, fast, or they'd start to rob and plunder the country areas. The people who depend on government paying for their lives would be drawn to the welfare cities, which presumably would be in the North, at least, and how they'd pay for food and needs of people who do no work, I don't know. Probably wouldn't, for long.Can you imagine the exit of taxpayers and the influx of welfare queens to the Communist states?
The nation of Democrat controlled states would be a third world shithole within a couple of years.
