You mean, when capitalism isn't bringing unprecedented amounts of people out of abject poverty? (eg, cutting world poverty in half in the past 20 years)
Socialism is great, until you read a history book or look at its actual implementation. And no, don't bring up northern EU states that actually depend on quite free market capitalism to finance it (as well as unrealistic monocultures that are unrealistic for the USA, and lead to morally reprehensible immigration restrictions to keep the systems from being overwhelmed)
