Again, Steve's Progressive instincts cloud what remains of his judgement. A government's capacity to impose taxes has nothing to do with the quality of the real economy it oversees and everything to do with its sovereign power.
I've been looking at Waldman's article off and on over the past many days, but have been unable to give it any real attention, in the press of other things, which is not going to get relieved any time soon. Oh, well. So I can't add anything meaningful about the pros and cons of MMT, or anyone's view of it.
Further, I only discovered Winterspeak fairly recently, and haven't read enough to form an opinion of the views and/or viewpoint expressed there. However, a couple of things strike me wrong about the above quote. First, does progressivism really cloud judgment? Sure, a dogmatic clutching at any ideology can lead to a negation of reality, whenever it comes up against the tenets of the one true faith. But isn't an open-minded and pragmatic inquiry into the real nature of things a trade mark of progressivism? Not that any way of thinking has a corner on the truth, but suggesting that progresivism is an impediment to seeking the truth smacks of ideological claptrap.
More importantly, the dogmatic statement about the nature of taxation is simply wrong. Sure taxation policy is a vital element of sovereign power. But to suggest that tax policy is irrelevant to the quality of the economy is nonsense. Besides funding the government, taxation always and everywhere accomplishes some sort of wealth distribution. The government does more than just engage in warfare and maintenance of the nation's physical plant. It buys stuff, it lets contracts, it employs people, it provides medial care, food stamps and, best of all, Social Security payments to old fogies like me. The latter two are particularly effective ways of getting money to flow into the economy. I certainly spend every penny of my SS check.
So - sorry Winterspeak - poorly thought-through, and badly done. I wonder why? Could your ideological instincts be clouding your judgment?
