While slogging through an economics course in college I was frustrated that there were not teaching me anything. Then I discovered Sowell and Friedman and started watching every video I could find. Such a relief.
I just did what they wanted me to do for the rest of the economics courses but basically just ignored it all. No one in academia or the media wants to hear what Sowell and Friedman have to say. I should have been made aware of these guys and been assigned books and videos from them on day one.
