You don’t get to fly to most any other country without permission, you’re talking about the walls in the Soviet Union, which were both anomalous and rare in socialist history, and had absolutely nothing to do with Marxism itself. No group has ever stood against the slavers more than the Marxists, you wish to speak of slavers? Talk about your entire global economy, talk about where it gets its cheap labor, how america made Libya so broken that open air slave trade came back, talk about that ever so often. People have risked EVERYTHING fleeing capitalist countries with fascist regimes in place, Nazi germany was fascist and capitalist, people have been trying to go BACK to North Korea for employment, people have CHOSEN Cuba, China, the USSR, and many more over capitalist nations, don’t speak to me of risking everything.
