Friedman hasn't a clue. He is looking at politics from a very privileged upper middle-class position, where he gets paid to produce theoretical fairy tales. What both the Sanders and Trump campaigns are about is a revolt of working-class people who are struggling to make a living and survive, and are tired of being screwed by the establishment, both Democrat and Republican. Sanders offered real solutions, which unfortunately a national majority of Democrats did not buy, while Trump is a fraud. 

Contrary to Friedman, the solution is not more education. Most high school grads are not going to spend even more time sitting while someone talks at them, and it wouldn't do them any good if they did. Nor is so-called "free" trade that allow corporations to keep wages low by threatening to move their factories to other countries with dirt cheap labor.
