My favourite liberal philosopher of recent decades is Richard Rorty, who died in 2007.
An article by Mark Danner in the New York Review of Books quotes a passage from Rorty's 1998 book Achieving Our Country: Leftist Thought in Twentieth-Century America:
Watching him blather and mug as he casually leaned over the podium in Boca Raton, seeing him cultivate the applause as if directing a symphony and then raise his two hands in thumbs-up gestures as he surfed the waves of applause and the deafening shouts of “USA! USA! USA!,” I recalled a remark that the philosopher Richard Rorty made back in 1997 about “the old industrialized democracies…heading into a Weimar-like period.” Citing evidence from “many writers on socioeconomic policy,” Rorty suggested that
members of labor unions, and unorganized unskilled workers, will sooner or later realize that their government is not even trying to prevent wages from sinking or to prevent jobs from being exported. Around the same time, they will realize that suburban white-collar workers—themselves desperately afraid of being downsized—are not going to let themselves be taxed to provide social benefits for anyone else.
At that point, something will crack. The nonsuburban electorate will decide that the system has failed and start looking around for a strongman to vote for—someone willing to assure them that, once he is elected, the smug bureaucrats, tricky lawyers, overpaid bond salesmen, and postmodernist professors will no longer be calling the shots….
One thing that is very likely to happen is that the gains made in the past forty years by black and brown Americans, and by homosexuals, will be wiped out. Jocular contempt for women will come back into fashion…. All the resentment which badly educated Americans feel about having their manners dictated to them by college graduates will find an outlet.
As Trump put it in Nevada, “I love the poorly educated!”
