"Marxist liberal world order"? Marxists aren't liberals and liberals aren't Marxists. Corporatism is the new world order that has supplanted nation states, more or less. Corporations have all the rights and none of the obligations that people used to enjoy. They are blithely destroying the oceans, the land, and the air in their endless lust for profit with the aid of their bought-and-paid-for politicians. You are right about one thing which is that America is "sliding down" the hill towards outright fascism, but it is about the unbridled power of capitalism and not the rise of a worker-controlled state, i.e., a Marxist socialist state.
