The idea of communism (extremely simplified) everyone has the means to live and people at “the top” don’t get special privilege on that, obviously almost all actual implementations turn into dictatorships so the point is somewhat moot, however the fact a well connected diplomat in a communist country had to live in the same conditions as other non-well connected people would be a positive, not a negative, they’d see and hopefully be able to improve the lives of everyone as they understand what it’s like.
Compare that to a majority of the rich and powerful in America, they’re so ridiculously disconnected from the average experience that they literally do not understand at all what it’s like for those with less.
