"... consisting of people who feel that things to which they are entitled are being taken away."
If I am rich in America, chances are that either I, or my family before me, earned the money in the most effective free market known. I'm not saying it's perfect, but it's the best we've got. The assertion that I should be able to keep what I have earned is not entitlement. Entitlement is the assertion that I have a right to something, without regard for effort or trade.
I am entitled to keep what I have earned. Taking my earnings is a moral wrong. There is no two ways about it. It is no more right to take a dollar from a man who has a hundred of them than it is to take a dollar from a man who has one.
