I must say I'm having a hard time deciding whether or not to even bother finishing this book. Krugman is petulant, and uses data (whether or not it is reliable data) toward his own pre-conceived conclusions. There are many, many sections where he contradicts himself, or otherwise ignores facts that don't fit what he's trying to accomplish.
Through past works, I've come to know Krugman as a talented economist. He bastardizes his expertise with this liberal feel-good book. Now that Obama is trying to repeat most of what Krugman advocates, we'll see if he owns up to the coming failures.
