Simple..they have been brainwashed by Communist professors who have taught them that Capitalism is evil and Communism is super awesome..that they will get everything for FREE, free school, free car, free home, free health care, free everything..all they have to do is embrace Communism, where the Govt controls everything, just give up your freedom and you can get everything you desire for free
Unless freedom is the only thing you desire.
It is romantic to them. That is what lures them in.
