Let's assume, that USA of Great Depression era were invaded by early-1970s USSR. This would be pretty good model of Manticoran occupation of Silesia; prosperous, vastly superior technologically and industrially society occupied the almost-failed, defunct and outdated state. Of course, the 1920s USA military could provide no more than token resistance against 1970s superior Soviet military (exactly as Silesia against RMN), and the essential parts of the country would be quickly put under Soviet control.
Would the invasion be beneficial for 1920s USA? In purely economical and social therms, yes. From 1920s - especially Depression strike 1920s - the USSR of 197s would looks like a technological and social utopia.The average soviet worker in 1970s lived in prosperity by the 1920s USA worker point of view. The average Soviet citizen of 1920s never faced hunger, never ever feared to lose his job. He have perfect social protection, guaranteed by the state itself. From the 1920s point of view, the 1970s Soviet worker have a granted acces to futuristic, superior medicine, excellent education, equival career opportunites, ect., ect., ect.
Of course, implementation said superior system in 1920s USA would means some downside, too. For example, a relatively small part of population - remaining rich peoples - would losse a major part of their wealth. But it's okay, because the expropriated wealth would be given back to workers, from whom this wealth was extorted by greedy capitalists. You probably would have only a single - Communist - party, but that's okay; after all, the USA have only two parties that really means, and both of them are corrupt and incompetent, and only protected the capitalists. Of course, your military would be placed under general USSR control - but again, for what USA of 1920s used their military, other than to threaten the weaker countries?
So, it seems that such occupation (1920s USA occuped by 1970s USSR) could be really, really good thing, right, comrade RFC?


But for some strange reason, RFC, I doubt that you would agree...
