The left is actually right that society would be better if the “best and brightest” made all decisions. Of course they are wrong that the “best and brightest” is them.
It really depends on what you mean by a “better society” and the arrogance of anyone who believes they have that answer. The pursuit of happiness, if we accept that as a God given right, is an individual determination. I don’t need someone else’s idea of utopia to be happy and I can be happy without denying anyone their rights. I would be quite unhappy to be directed by someone else’s concept of happiness.
