Cheaper than Ec 10

Here you can buy 10 economics lectures for $1.60 per lecture.

By contrast, Harvard tuition is about $30K (not counting room and board). Assuming 4 courses each of the two 12-week semesters and 3 class hours a week in each course, one finds that each hour class at Harvard costs about $100--roughly the same price as a good ticket to a Broadway show.

I suppose there is something special about live performances.
