Capitalism dead socialism the solution?

why is it that many young ppl are becoming more socialist now? everybody says that capitalism is evil and obsolete.or its inhumane. a see a lot of ppl wearing the che guavara shirt and what not. is it because of Micheal Moore's sicko? is socialism the answer or a mix of both cap and social? or is it just corporations are too powerful and bad.but then you could argue "how did they get the freedom to be so rich in the 1s place"
