I just saw this excellent Imprimis interview with Milton Friedman. It took place in 2006, but the issues Mr. Friedman discusses are relevant today. He talks about reforming the Middle East, reforming medical care (which he calls a "socialist-communist system"), and extending school vouchers.
My favorite quote: "Self-interest, rightly understood, works for the benefit of society as a whole."
Here is my book review of Capitalism and Freedom, Milton Friedman's short, seminal book on economics and freedom.
