I don't know for sure, but I do know that the modern Democratic party is somehow radically to the left of even Karl Marx on that point.
Marx advocated
"from each according to his ability, to each according to his need."
That is apparently just too right-wing for the Democratic party, which instead champions from each of the 51% according to their ability, and then some, and to each of the 49% according to their every want and desire, whatever it takes to get the votes.
Insane.
