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.

This is very true. It's a very interesting exercise to go back and read old copies of the Congressional Reports and compare them to ones from today. Back in the 1940s, Republicans would say things as lip service to prevailing views about labor that democrats wouldn't say today. Big sweeping appeals to the public interest in the way today people make narrow pointed arguments about efficiency and cost-benefit analysis.
Topologically, the Left pulled farther and faster, and there was also a reaction to that.
Industry became fragmented, and that's much harder to organize into unions. It was different when there were a small number of large monolithic firms.
This being said, Progressivism has a checkered past. The bleeding edge is a fickle hellcat, full of bad normative assumptions. A devout New England Abolitionist would have thought nothing of beating the Irish in his employ severely. Stuff like that.
Add to all of this the consequentialist tendencies in the political discourse.
Why do you think that? I'd say almost the opposite, that societies are not "intentionally designed", but evolve from myriad people and "accidents" of history.
Design in general is bad, if the design overrides all other measurement and input.
Wasn't More's book a reductio anyway?
There's no such thing as a Platonic form.
Societies are always and have always been creatures of intentional design. The design might be good or might be bad, but to try to cordon off via, "Designed societies are bad" just amounts to denying the design of your preferred actually-existing society.
