Marx had its own version which was somehow similar to that of Plato's. B. F. Skinner believed in human engineering, further detailed in his Walden Two.
Karl Marx's version is capitalism, which is showcased in a couple of societies seen nowadays, and was practiced in Russia in the olden days. Communism looks good on paper, but we all know how it works in the real world...
This sounds like a similar idea - an idea of a utopian society, which just seems unachievable to be honest. This requires basically, that governments and rich people give up their power, and stop abusing the environment, and move to a more organical based environment, which just doesn't seem feasible, no company is going to give up profits to help the environment, we've seen this happen already.
