In reality, however, the opposite happened. Russian potato farmers without any machines or capital started industrialising the moment the communists took over.
Communism is a dead ideology, because it failed to evolve in the face of reality disagreeing with the communist world view.
Communists think that capital grants its owners power and that competition leads to exploitation, when the exact opposite is true.
I'm more careful with those kinds of generalizations these days than I used to be. As a rule, Trump-like demagogues don't win elections in stable, prosperous societies, either. It always takes some kind of crisis -- a lost war, oppressive debt, ruined national self-image, runaway inflation, intolerable abuse by the incumbent regime -- yet here we are.
Propaganda is more powerful than I thought it was... and who's better at propaganda than the Communists?
Now let's also give the benefit of the doubt to the author of the comment, and suppose they were pointing to Mao's governance period, rather than communism at a general level. And even if they didn't, that still something to consider actually.
Communism does not take off in stable prosperous societies because there isn't a market for it. It quite literally requires an underclass of people unhappy enough to stake their lives on establishing a different social order.
