The radlib description of a future socialist society is just the same as present day liberal society. There is no philosophical maturation from the thinking of liberalism. There is no new evolved system/method based in scientific principles that these "socialists" have created. Just a wishlist. Truly, what a future.

Furthermore, legally speaking, most of these liberal rights can be found in most of the liberal societies. So why is this radlib so dissatisfied at all?

It's pure liberal idealism intersecting with the material reality that liberal systems don't actually live up to their propaganda, in someone who also uncritically accepts liberal propaganda as true. So you get this contradictory "the American Empire is the true successor of Karl Marx's legacy with all these slow incremental reforms that just like happen because of vibes or something idk why things happen or what material causes are, all I know is it can be better if we all do the magic vooooting ritual with more purity and faith in the system in our hearts!" gibberish right alongside aggressive contempt for the empire's victims and for any socialist project that just did good things and made things better for its people because they didn't follow the American-prescribed system of letting America say whether they could or not.
