If the list goes on, you could have then easily picked better examples, couldn't you? When North Korean society still had any meaningful relationship to socialism (not communism) it actually had a higher GDP than South Korea. It only turned around in the 70s and 80s when NK leadership structures went completely insane.
So, what other systems? State socialism? It can only be viewed as an alternative system to liberal capitalism, not to capitalism in general sense because it still leaves the same economic relations basically intact. It's an incompetent, extremely monopolistic form of capitalism, which is why it failed so miserably.
Maybe I wasn't clear enough in my last paragraph, so I apologize to you, but I was thinking of something that didn't fundamentally had anything to do with capitalism. This example still clings to erroneous notion that state socialism is something fundamentally different. It's not really. Of course liberal capitalism outperforms state run centrally planned parody of capitalism.
