Think of the exodus from the US to Canada. Most people in the USA, 99%, just want their ordinary life.

The Jan. 6 rioters were small business owners…but there is only so much that they can do if they teamed up for civil war. They would team up with Billionaires to kick the balls in of blue collar workers. The war would destroy state/federal institutions that license workers like nurses and doctors.
Essentially this war is about the Karens fighting to run an HVAC business with unlicensed workers. Eventually the licensed workers would be divided between those that can stand up to the mean Karens of he world vs. those that can’t. Doctors, machinist, would eventually be paid by the state an o.k. wage, while HVAC and such would be run by gangsters. See Venezuela, Iran and old Chile.

The dog catching the car…what do you do with something like NYC. Even if you win? Where do the new doctors graduate from? Nurses? Who certifies them? Same with electricians, carpenters, gasfitters, HVAC and plumbers? Those blue collar jobs would have their professional credentials destroyed, and be forced to compete with every general contractor… a race to the bottom. Sophisticated technology would stop operating after awhile, and with the loss of the supply chain and licenses/regulated manufacturing facilities nothing in the U.S.A. of substance would be built. Only those in the army would be paid. Essentially you’d get N. Korea, fascist Spain, Venezuela or an Iran, like country. Mass migration out.

Russia in the 1990s, Haiti, Somali, large occasional power outages. Things go on… Cities are so large that they still somewhat go on functioning; education, hospitals, public transport, local shops. Because what is there to do otherwise? Small bands of armed bandits cause most of the problems, but that never last too long, killing each other. Small regions that break off suffer the most, as resources in those locations get scarce, they get overrun constantly with armed bandits. Small communities start to protect themselves, eventually successfully, and work to re-establish relations with the larger cities.
Most people that can. leave. Wars then go on based on funding from outside interests.

It was the 1915, Hollywood movie ‘Birth of Nation’ that re-invented and restarted the whole southern states thing. One, of only a handful, of movies that year, almost the entire population of the U.S.A. watched it. This was when full length movies a medium was still new and influential.
