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.
I've made my peace with not surviving it. My comrades are all too far away from to be of use to survival. The literal only thing between me and the fascists is maybe three or four remaining chosen-family members and my tools, so... I resolve to at least be expensive to whoever's pressing me before I go.
