All 3 of the countries you bring up are different. Russia is the most likely to have a revolution, while the PRC and DPRK are the least likely, less likely than countries like the US or UK.

Russia is currently in the position its in because capitalism was devastating for them. The west came in and plundered and looted the former productive forces until the nationalists kicked them out (Putin's faction), running themselves into an even more hostile situation with the west. Communist party membership is rising, soviet nostalgia is rising, and now even the ruling class is paying lip service to Lenin, Stalin, and their soviet heritage.

China is not going to have a revolution because it's socialist and the system works for the people. It's plain and simple, the people support their system at a far higher rate than western countries:.

The DPRK is in a situation similar to Cuba. It's heavily sanctioned, but does fairly well when considering just how devastating both the Korean War and the Arduous March were (in the 90s, when the Soviet Union fell). Its economy is growing around 3.5%-4% per year, and food is relatively secure now too. The people blame the US Empire for the lack of their ability to trade and sell outside, though they now do trade heavily with Russia and China, meaning they are less likely than ever to revolt.

Neither the PRC nor the DPRK are perfect, of course, but they are far from revolution, not because of something like "propaganda" but because their systems don't work like you think they do.
