People like to think like that, because they want to preserve their money on the off chance they become millionaires. The vast majority however do not. It's American capitalist brainwashing at its finest.
Personally I'm very much in favour of taxing the very rich very heavily. Anything to protect the middle class. It's what keeps your society sane.
What I hate about Belgium though, and by extension Europe, is that we tend to get all of our tax income from the upper middle class. And that takes away any incentive to try and better yourself really, because the minute you start making decent money, you have to give away so much you are only barely better off financially.
