It appears to me that the complete deindustrialization of the imperial core is a historical arc that, since 1973, has been more or less unstoppable. The question is, if a socialist world revolution were to happen in the near future, and they basically established JDPON, how would it be possible to reindustrialize the former imperialist nations without relying on exploiting the former periphery countries? The actual productive capacity has been decimated.
Yes, tremendously easy with internationally coordinated central planning.
The US and Canada have a wealth of mineral and energy reserves, as does Australia, in addition to significant agricultural capacity.
Consumer goods would diminish (at least the short term, unrepairable gizmos that dominate consumerism) and there would need to be significant retraining away from bullshit jobs, but the progress of the USSR in 20 years - without 170 years of capital accumulation - is instructive.
