It is an awkward truth that totalitarianism can arrive under any kind of banner. It is also an awkward truth that that there are few things more illiberal than a liberal with the bit of truth between their teeth, but it doesn't follow therefore that Milton Friedman makes more sense than say JK Galbraith. This won't do David. The rule of law and the constitution are indeed powerful and vital for our political health and wellbeing and when the rich and powerful stop subverting it for the benefit of their bottom line and when the disparity between rich and poor stops widening, I'll be more inclined to feel persuaded.
With David Mamet's royalties and his ability to feel like the king in his own little fiefdom it's probably easier to believe that life is good, while also confusingly subscribing to the Hobbsian view of nature... He has crawled out of the pit, so ergo it's a fair result? Human nature, is more probably both a biological given and socially conditioned... the one doesn't preclude the other. I suggest that Mr Mamet spends a fortnight living in the same conditions and on the same income and with the same pressures as one of the "undeserving poor" his new friends on the right talk patronizingly about - say, a single parent adjunct professor with two kids, no health insurance, and a wage packet well below the poverty line, and see how long it takes before he reconnects to the idea that social justice is more than just two lazy words uttered by the brain dead. Social Justice does mean something David - but you can't understand what it means while being fitted out by the same tailor that the Emperor who wears invisible clothes, visits.
