Alas, given that human nature hasn't changed over the six thousand or so years we have evidence for, the idea that it might change in a fraction of that time seems improbable to me.
No economic or political system has really ever survived for more than a couple of generations before the, for want of a better word, sociopaths figure out how to game it. The lucky periods are the ones where the new system was largely already ready to take over; most of the time, however, bloody revolution (or, worse, full-scale war) was necessary first.
I admire the optimism in this piece, but it feels to me as though we're already too late. Part of the problem is that the political systems in the US and the UK particularly (but elsewhere too) are disintegrating, meaning that the politicians who are supposed to monitor this sort of thing are being a little distracted (and/or being bought off, although I think that's a lot less of a problem than it is sometimes made out to be.)
