Over the years, I've asked the few economists I've run into why "economic growth" is so important, i.e. why everyone cheers when we're growing 3%-4% a year, and cries when we're not. And I've asked that question for a very specific reason, i.e. I find it fascinating that it's one of the rare subjects that Republicans and Democrats agree on. They agree that on-going, year after year "economic growth" of at least 3-4 % is vitally important, and that it is a very good thing. (As too do the Liberals and Conservatives and NDP agree in Canada; and the Conservatives and Labour and the Liberal Democrats in the UK.) Few else seem to find this unanimity of opinion strange and vaguely unsettling, but I do; I find the overwhelmingly strong consensus, this set-in-stone conventional wisdom very strange -- and, truth be told, I'm suspicious of it, as I am of all conventional wisdom. Anyway, not one of those economists ever gave me a satisfactory answer; maybe I was talking to dumb economists, maybe I'm too dumb to understand what they were telling me (and that's not false modesty). But I'm still left with this conclusion (as it applies to this thread): there are a whole bunch of very smart and very well educated posters on this board sure that they are looking deep into the heart of this issue/question, but I have a feeling that none of us is looking nearly deep enough, not nearly deep enough into the underlying structures and assumptions of modern economic life, globally. But then again, I have always been of the view that economics is not a science but an art, and that you couldn't find anything more unlike the "law of gravity" than the "laws of economics".
