Fortunately the options aren't merely some form of marxist communism or capitalism! There are whole branches of (anarchist/federalist) socialism that actually predicted what would happen in the Soviet Union while Marx was still alive and writing and had very different plans themselves (Bakunin and Proudhon), and there were also distinct forms of socialism that predated Marxism, and forms that came after it, so even if we were to restrict ourselves to socialist schools of thought that have existed for round about 200 years (a very narrow slice of economic systems), there are a lot more options to try than "bureaucratic oligarchy, with a top down centrally planned economy and a fundamentally authoritarian ideology" and "a system designed to give some power over others via absentee property ownership, and facilitate the concentration of that power through the concentration of property due to the right of increase and profit."
