I highly recommend The Forgotten Man by Amity Shlaes. I've had it on my night stand for some time now, intending to read it to increase my understanding of the Great Depression. She argues that many of the government's actions not only failed to cure the Great Depression, but made it worse.
When I finally picked it up yesterday, I was so startled by the parallels in what she describes to what's going on today that I wrote this short piece that has been published by The American Thinker. Down to the presidential urge to expoit the opportunities inherent in crisis situations and the governmental itch to micromanage businesses, it's uncanny.
