The US has largely trended more authoritarian So, you agree with him. The left has ALWAYS favored authoritarian government from the days when the terms left and right were first used about politics during the French Revolution. Progressives believe that the government should employ "experts" who will tell farmers what crops to plant, when to plant them, when to harvest them, and how much to charge for them. They believe that the government should have experts who determine what the best diet is for people and enact regulations to make sure that people eat such a diet (or are penalized for not doing so). There is no area of life where progressives do not believe we would be better off doing what government experts instruct us to do rather than what we personally desire and that therefore the government should punish us, for our own good, when we do not follow the rules defined by "experts".
Ever notice that even the busiest people are never too busy to tell you just how busy they are?
