If you had a great new idea in the Soviet Union, for example, do you suppose you would be just given the resources necessary to execute it well? Of course not, and moreover the incumbent solutions were a lot better positioned to crush your novel way of doing things in order to protect their own positions than the incumbents are under capitalism.
The Soviet Union was a variation of capitalism, called state capitalism. I hope you weren't implying that they were socialists or communists in any way. We have not seen socialism, only small forms of democratic socialism. We have definitely never seen communism, only dictatorships and their one-party systems.
Back in the late 90s I worked at a US bank with an older and wiser dev who'd done long stints at DEC and IBM. HE used to comment that it's no accident that IBM nearly collapsed at the same time as the Soviet Union actually did, as they were very similar organisations :) I guess Lou Gerstner was a better turn around exec than Gorbachev.
Let me state it explicitly: that "state capitalist" theory is false (and so absurd it makes me suspect you are part of some sort of Russian troll farm.) The USSR was both socialist and communist in character, and not at all capitalist.
