The ultimate goal is for the government to have control of all of the means of production. See the communist manifesto.
The ultimate goal is for the corporations to retain the means of production but the decision-making rests in the hands of the government. In other words, fusion of corporation and state. This is Fascism.
Unlike communism, fascism was a very successful economic model besides capitalism. It worked successfully under Hitler's Nazi Germany, Mussolini's Fascist Italy, and to this day, under Japan since WWII.
So I figure fascism would work successfully under Obama's America.
Anyway, fascism will be the new world order's political and economic model.
