And that's where your premise is flawed. It's not that they don't understand it. It's that they don't care. As Baraq Obama said himself to Charlie Gibson back in 2008:
"Well, Charlie, what I've said is that I would look at raising the capital gains tax for purposes of fairness."

I know some of it is in the name of “fairness”. But a lot of it really is an inability to understand the simplest and most basic of economic realities, that people aren’t going to work for nothing and that rich people aren’t going to sit in one place while all their money gets stolen.
Where are they going to get that understanding? In the government schools?
