I'm not quite sure what you deem socialism. Let's speak in examples.

"Mikhail Gorbachev wished to move the USSR in the direction of Nordic-style social democracy, calling it 'a socialist beacon for all mankind.'" -Wikipedia

Does that mean that the Nordic Model is a form of socialism? Just pick-up any metrics for life quality, and nordic countries (and nordic-minded, such as New Zealand and Netherlands) are sure to top it. I think that has to prove something.
