I've noticed that all the people I knew in college who now claim to be communists are all the people who... are not very community friendly. As in, they never pull their own weight in a group setting and they always want their own separate everything (bedroom, bathroom, kitchen... house... popcorn at the movies). But then on top of that they don't want to go to work anymore because "it's a capitalist scam." 

I'm no expert on communism, but I'm pretty sure even in a communist utopia you can't just sit around all day.
