European social democracies have made it work by continuously re-constructing it. Employees and citizens of the welfare state are at the table when negotiating how to set rules for the managed capitalism. Check out Sweden for example.
I'm actually from Poland, a country that had actual communism created by another rich jew that wanted to help "the opressed masses". You think at the beginning any of the commies said straight what they plan to do how it will look like after they're done? And what they will do with the evil burgois (or "the 1%" as Sanders and his cultists name it). You're playing with fire, just be wary.
