To pop your bubble: How much CO2 does the average american emit compared to the average European or Chinese person?

Those were all government regulations. CFC's didn't magically disappear trough a tiny fraction of the world knowing how they impacted the ozone layer and being rational consumers.

You seem to have very little idea of what Marxism is, so might want to research a bit further on this part before making such a black-and-white conclusion. What happens in China today has little to do with Marxist ideology, but rather is a plain and simple dictatorship that has long adopted a capitalist economy. Both on the political and economic front China has little Marxist ideology left, except for the language they adopt.

You could've just said "china = bad; people I don't like = bad" and spared everyone's time. Nothing of worth would've been lost

I moved to and have been living in an EM country for ~6 years and tell my wife (whose from the EM country) something like this occasionally: "If the leaders want to adapt "green" policies uber alles, they'll be hanged in the street with their friends and families faster than takes for their doomsday predictions to come into fruition than the current status quo of slow progress. If they really want people to adapt "better" solutions, they would need to make them cheaper and more accessible than what exists today".

I'd argue the same is true for even DM countries who have populations that have grown to expect even more…

How did you get from Social Justice to Marxism? Those are two different ideologies with different goals and little overlap, except that both require strong, authoritarian states to achieve their agendas.
