And the milieux that circulates this is really primarily liberal, centrist in practice, overwhelmingly supporting and electing quite mainstream fully "capitalist" political parties... but with the aesthetic or appeal to a past radical, anti-capitalist, socialist "scene"... without an actual meaningful program or alternative for the working class. A working class which has as a result almost completely divorced itself from this "left."
Which is all the end product of the demolition of the organized socialist left & trade union movement in the west through the 70s and 80s and early 90s and the retreat of associated intellectuals into academia and cultural politics.
If, as I keep hearing from right-wing commentators, "the left" is somehow dominant, it's only because "the left" has wholesale dropped its historical anti-capitalist mission, and has retreated almost exclusively into culture wars; and generally taken positions which enrage the right on that basis, but doesn't actually challenge any real power. A very general "anti-oppression" politic which is primarily concerned with individual concerns, not collective ones. This "left" that I keep hearing about from the Shapiro etc types foaming at the mouth, it's a caricature not only made by its opponents... but by itself.
Just Liberalism, and a very 21st century American product.
