“Free” has a lot of definitions. But to BreakThru Radio this week, it stands for a free economy—a society where people, products and labor are all free. On Book Talk, I review a newly launched website by BTR’s own Sam Griswold that scores books for free. I review Nelson Mandela’s fight for freedom, and the state of South Africa in the state of his looming death. Finally, I look at how a Reverend from Brooklyn, NY argues for the morality of a free-market economy.
