Because they are shitholes. Nobody wants to emigrate to communist countries. When the wall of Berlin fell people ran to capitalism not the other way. I don’t see boats of Americans going to Cuba. Do you see English emigrating to Poland to work in construction?I agree with this. Voxday made a compelling argument recently that "Capitalism is worse for your country than communism". Capitalism invites immigration, and destroys nations. Communism kills en masse yes, and it also destroys the economy, but Poland is still Poland, Russia is still Russia, China is still Chineese.
