>I think Bernie Sanders went too far in some of his policy proposal, but I wouldn't characterize him, or progressives in general, as promoting a utopian Marxist vision.
Very much agreed. From the point of view of actual radical leftists (for instance, the ones I grab beer with once or twice a month), Bernie Sanders is very much a moderate, even a kind of conservative. In trying to expand the sphere of public goods back towards where it has previously been (in some places and times) and a bit past that, he's just trying to turn our market society[1] back into a market economy subservient to a democratic society.
Correspondingly, we also need to consider the degree to which, while we don't live in Friedrich von Hayek's or Milton Friedman's ideal society, their ideas now exercise far, far more influence over our society than they did at the inauguration of the Mont Pelerin Society[2]. These men plotted utopia, and to a great degree, they've achieved it, exactly insofar as the social democrats whose hegemony they wanted to destroy are now seen as unthinkable radicals dreaming of utopia.
