To speak of "abandoned socialism" presupposes that there was some socialism that was abandoned. That is quite an exaggeration. There have been moves towards traditional socialist ideals of the kind described by Dewey - who I quoted not because the observations are original, but because he is America's leading social philosopher, "as American as apple pie," in the standard phrase. Such initiatives have often been demolished by force, not only in the West. The first acts of Lenin and Trotsky after taking power were to destroy the factory councils and Soviets, and in fact just about every socialist tendency that had developed before the Bolshevik takeover. From then until its collapse, the Soviet tyranny was one of the major anti-socialist forces in the world. But nonetheless, there were elements of democracy and socialism (in the traditional non-Bolshevik sense), including self-management in the former Yugoslavia, though it was severely flawed because of the more general context of centralized authority within which it was embedded.
