For people living in non-imperialist nations, the fall of imperialism will probably make life somewhat easier, especially since it will make the transition to socialism much, much easier.
Many of us do not live in a communist country and do not have the opportunity or desire to move to one. Therefore, we must stay at home to fight to liberate our homeland.
Because of how bad life is going to decline, what can we do to survive financially, mentally, physically, socially, etc? What can we do in order to help liberate ourselves and our nations?
Perhaps we can look to our comrades many decades ago who conducted successful socialist revolutions in the past for inspiration, like in Cuba, China, Tsarist Russia, African nations, Indochina, Korea, etc. They were fighting in conditions much more dire than ours, or possibly even more dire than our future situation.
One solution is to replace the inferior Capitalist system of rigged elections and plutocracy with meritocracy and democracy that does not depend on rigged elections. The USA depends on rich natural resource, stolen fertile land, good climate, and strategic trading locations for compensation to their poor politico-economic system that sustain a few free riders. If the imperial core get rid of the system that support the lazy rich 1% with a democratic and meritocratic system, then the proletariat in the imperial xore could survive the lost of imperial free riding privilege from Pax Americana and Bretton Woods institutions.
