This is why I am asking you for a time period. The transition from capitalism to socialism in the imperialist countries would likely result in a shortage of endless cheap commodities, while expanding social safety nets. In the medium to long-term, quality of life would improve as the world would better be able to produce and distribute for everyone than is presently available. Imperialism holds the global south back from economic development for the short term gain of the imperial core, but a world aligned can better develop and produce.
