To be honest, if the leftist revolution promises Stalins USSR style economics and governance, then Western people are better off without it because most people in Western nations are relatively well off, so moving to that type of economic/political model will make the majority in a western nation poorer.

For example, 66% of US population are homeowners, that is they own both the land and property (if any). In this case, the humanitarian pov is that the minority should be lifted from poverty, and provided equal rights to achieve self-actualization. So housing assistance, education, health care and food assistance.

The democratic and humane way to achieve this is via high tax rates on the uber wealthy. People also deserve protections from discrimination to enable their self-actualization in a psychologically and physically safe manner. My own philosophy is that a person is born without any will to be born, so that person doesn’t necessarily owe anything to anyone else other than reasonable and mutual social contracts. People don’t have the right to be sociopaths or psychopaths, but they don’t have to be self sacrificing or altruistic.

My own pov aside, the U.S. could implement China-style market socialism and state-controlled socialism for itself and its citizens, but then it’s not going to be a haven for immigrants because such policies require cultural homogeneity. Cultural homogeneity requires strict immigration control, as seen in China, https://www.ispionline.it/en/publication/why-isnt-china-considering-immigration-against-demographic-decline-163101.

But I think maintaining immigration to democratic and economically well off nations is important for lifting the world out of poverty and illiteracy. However, all of this necessitates that nations preserve democracy. Capitalism has ruined democracy, which is why we get neoconservatism/neoliberalism, two sides of the same fail coin.

Governance models have forgotten that people formed groups, communities and nations to ensure the betterment and self-actualization of the individual, not to create productivity or workers. Currently the world acts to enable self actualization for companies or nations, which is why we end up with genocides and corporate imperialism as a default state. People deserve better than the Stalin-style leftism or the Clinton-style liberalism. I think we need some type of humanitarian libertarianism, where we can ensure free markets, individual freedoms, but also governance models which ensure social fairness and justice.

People who seek first to run away to greener pastures rather than try and maintain their own are the true scourges of society.

From my casual observation, leftists tend to be a lot more individualistic and tribalistic than people on the right, to the point where they would much rather join the right just to spite another left group.
