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."
Capitalism appears to have worked optimally around the 1960 to 1990 time interval.
After 1990 a consolidation process became more and more obvious and it has accelerated greatly after 2000. The long sequence of mergers and acquisitions has resulted in the fact that most markets have become dominated by quasi-monopolies, which some times resemble more the monopolies that existed in the industries of the countries dominated by communists than the multitude of competing companies that existed in USA or in Western Europe a half of century ago.
We've had communism in my country, never again.
