Cause Marxism has worked so well everywhere
You can laugh all you want, but, Truth can be difficult to face.
Here are some Marxist principles that are now very thoroughly embraced by the mainstream US electorate:
1) Government is the arbiter of Fairness. Society, especially US Capitalist society, has always been racist and unfair. FedGov's Job One is to fix the racism and unfairness and make us fair by compulsion of law.
2) Redistribution of Wealth is a great tool for FedGov to use to establish Economic Fairness. We need to borrow more and print more money, so that we can have even more Fairness. There are plenty of rich people to take from, and they didn't build that anyway, so, it is Fair for them to pay their Fair Share.
Do I need to continue? These are the first two principles of a Marxist persuasion that are well-accepted by a large portion of the US electorate.
