What communism means

Ask an average person (an American) what communism is and they'll say "it's something that's evil where the government tells you what to do". Isn't that happening right now?

With communism, people who aren't really interested in becoming doctors are forced into getting that education and doing work they don't enjoy simply because they have an aptitude for it.

With capitalism, people who would be talented doctors work for minimum wage their entire lives because they don't have enough money to go to medical school.
