“If Trump is impeached, the United States could face an opposite, yet potentially similar scenario. If rural people begin what’s effectively a mass general strike, urbanites won’t be forced out of the city by the government, they’ll be forced out by necessity. The price of food will skyrocket to the point of being unaffordable for anyone but the very richest of city-dwellers. Lines of production and transport will break down from lack of labor and self-sabotage, and the economy will begin folding in on itself.”

Unlikely. “urbanites” can easily get our food from Mexico, Canada, and other countries. In fact, a vast majority of our food is already coming from sources outside the US or from local farms being run by ex-urbanites. Your “us against them” narrative helps no one.
