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?

An ideal society would be where when every man turns 18 the government gives him physical and written tests to see what jobs he is best suited for. And if training is required they would give him training.

Of course if there was a shortage of certain jobs they would have to make exceptions they wouldn't normally make.
