The greatest value so far (and possibly in the long run as well) of the Occupy Wall Street movement has been not so much in the shaping of electoral politics — though it’s already starting to influence that somewhat — but in its shoving the Overton Window away from the far right end of the spectrum, far enough away to make talk of meaningful solutions possible, which is the first step towards making them politically viable. Putting a surtax on the rich and/or letting the Bush tax cuts finally expire was considered politically verboten as recently as a month ago. Then Occupy Wall Street got started, and suddenly surtaxes on millionaires start becoming very much discussed indeed.
