Thanks for the shout out Mike :)

I hope you enjoyed the Capitalism course. One of the things that surprised me about that course was although at first glance capitalism seems like a fairly straightforward subject, I felt like I had learned quite a bit from the course.

This was recommended in several posts by jrsedivy. The presentations are lectures supported by graphics and transcripts. Quizzes are available at the end of each course. I took the "Capitalism" lecture by Ayn Rand.
