The Mises Institute is running a 50% off summer sale on their courses, right now.
This means you can get The Road to Serfdom: Despotism, Then and Now, an online 5 week course taught by Thomas DiLorenzo at a bargain rate.
Details are here: http://epj.me/dilorenzo_road_to_serfdom
BTW, DiLorenzo is my guest this Sunday on The Robert Wenzel Show, where we talk about whether Nazi Germany or the current United States is more totalitarian, and what might start causing states to secede from the U. S. Is the U.S. headed for a Soviet Union style break up? DiLorenzo answers the question.
