Like even in the best of scenarios where the left isn't destroyed but can actually summon some form of revolutionary energy against capital, what is to prevent most capital investment from leaving the country as the winds begin to turn?
Is there good theory out there on how to prevent capital flight? Are there capital controls that don't simultaneously provoke capital flight?
The US has a highly financialized, service-based, and imperialism-dependent economy. If shit like that were to go down, it would be so much worse than simple capital flight. There would be no production to speak of to keep the lights on, it's 100% import dependent.
Better hope that other countries step in to supply capital and imports, e.g. China.
Edit: I assumed you were thinking of the US, which might not be the case.
