The very wealthy are so due to society. They profit the most (by definition) from society. They are defended by society (the sons and daughters of the poor, in fact). It is not only just, it is entirely in their interest to pay as much as necessary for society to continue. They have the most to lose. Playing apologist for the wealthy is about as pitiful as one can get.
Horseshit. That is a giant, steaming pile of horse apples. To say, "The very wealthy are only wealthy because of this society" is to say that there are no very wealthy people in OTHER societies. Likewise, the only definition by which they "profit most from society" is your own personal "I hate them because I'm not one of them" definition, and no one I would waste my time spitting on has any interest in living by your definitions. They are defended by society exactly as much as your worthless, sucking-the-intelligence-out-of-the-world ass is, and I don't see you suggesting that YOU should be stripped of your personal possessions (although I doubt the federal government has much use for your cardboard box and half-empty bottle of Ripple).
What is just is for fools like you to start producing and contributing something to make yourselves useful to society before you pollute the air with your greedy, jealous diatribes about how other people aren't contributing enough.
