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.
It’s pretty obvious I would have thought : Organise with other comrades to collectively own and run productive stuff that helps your standards of living. By pooling your resources with others, you get better outcomes. Those who only can contribute their labour will be more productive if they have access to collectively owned tools. They can still trade their labour even if the currency has gone to shit.
