To feel smart. Funnily enough, socialism really has it pretty hard trying to get off the ground. The US coups another nation every five years to install some corrupt dictator that's more than willing to sell out his nation to US interests in exhchange for power. So being hunted down and utterly corrupted by the worlds biggest terrorist nation, calling socialism "never truly tried" is kiiiiiiiiiind of correct. There is a lot of social policies in Europe and those worl pretty well, though US interests and their bootlickers erode those, too.
