Tried to explain communism to two kids. They said it is good if everyone has the same share of wealth. This even if one person works harder or is smarter.
So: why is communism bad? Is it because it never works in practice? Because it kills innovation? Explain it like I'm 8.

Also, I realize communism isn't 100% bad on paper. The q is for the thought experiment. Is communism bad because it went wrong and killed 100m people? Or is it rotten on paper too?
Points only for answers that don't tell the kids what to think.
