China also leaped from a colonized agrarian country to industrialized in a single generation, and Vietnam/Laos/Korea (both sides) were all similarly rapid. Cuba went from a primarily slave colony to a socialist country extremely rapidly as well.
As for the US, I think the leap would be similarly rapid. So much of the modern US Empire’s problems are caused by the decay in capitalism due to imperialism. Getting high speed rail, solar, decolonizing the Americas, healthcare, etc. would all be massive.
