The USSR and CCP were/are Marxist states. Saying they weren’t is just a cope from American socialists who feel the need to defend leftism anywhere, presumably because dumbasses think all socialists need to answer for every flaw while capitalism always has “context.”
Regardless, they, and various social democracies, did do something America refuses to, solve homelessness and hunger (after some… Initial difficulties).
I don’t particularly like the concept of the welfare state but it’s better than nothing and union busting.
