IF NOT CAPITALISM, THEN WHAT?

IF NOT CAPITALISM THEN WHAT? This is a fair question to pose, to consider,to ponder. Cannot a more equitable economic system be designed, be experimented with and, if successfully vetted in miniature, applied more broadly?. Capitalism is frequently criticized for its unevenness and its harshness. But in the absence of a more viable economic alternative, why? To what end? Surely. somewhere on Earth, in the long history of Earth, another more equitable, less exploitative economic system has prevailed on the Earth. What? Where? When? Whence? If this question cannot be answered, stop crying, criticizing. And get some!
