The great economic historian Robert Higgs was interviewed recently on C-SPAN2's "Book tv." The interview is three-hours long; every minute is worth watching.
As regular readers of this blog know, I greatly admire Bob's work (and Bob personally). His 2006 book Depression, War, and Cold War is just out in paperback; this book — data-rich and well-argued — effectively challenges the claim that the New Deal helped to improve the American economy during the 1930s, and the claim that war and military spending promote prosperity.
Oh, and his 1987 book Crisis and Leviathan is, justifiably, a classic.
