The problem is that, even though Capitalism is as broken, unworkable, and failed as a sustainable economic system as Communism, Imperialism, Colonialism, Mercantilism, Feudalism, and old-fashioned Barter or Pillaging/Looting, there's still a tiny minority of people in this world who benefit from IMMENSELY and IN SPADES from this utter trash heap economic system that is capitalism, and that minority either owns, or has huge influence, over most educational institutes, media outlets, political leaders (except the most extreme, radical, and marginal on the Right- and Left-Wings of the spectrum), and ALL financial institutions - elements which would be NECESSARY to have on board to institute these glorious new economic paradigms peacefully (that is, without a bloody revolution, and an utter crap-shoot of who will emerge on top of a new power structure when the dust settles).
