'The rich should pay their fair share' ?

"'The rich should pay their fair share.'
    "This term, 'fair share,' is an anti-concept. It's rationally unusable term designed to replace and obliterate some legitimate concept.
    "One legitimate concept is: the purpose of government.
    "Another is actual fairness. Fairness is when you get what you deserve. But in this catch-phrase, fairness is when you're harmed by the right amount....

    "What does fair mean [in this statement]? It means more. More than they currently pay. Then more than that. Then more again. A blank check until the rich are drained of all blood."
