Good point about socialism by experts.
One thing that the NW European experiments with socialism prove (including National Socialism 1933-1939) is that, if the voters believe, and act as if they believe, that they are members of an extended family that it can work.
Multiculturalism and socialism are not compatible. For a multiculti society, or a society with serious class divisions preventing the extended family metaphor from working, you need communism, which cannot be made to work.

That’s why the Dimocrat party platform mirrors the Communist Party USA’s platform ... their goal is and has been to drive us to Communism. Of course the only reason it hasn’t worked anywhere yet is that they just haven’t killed enough people ... 100 million dead more or less ... but who’s counting!!!
