Peter Schiff's Books
1. "How and Economy Grows and Why it crashes" for a nice really simple primer on Austrian economics (story of 3 guys on a desert island). Appropriate for bright 10 year olds to adults.
2. "Crash Proof 2.0" for an overview of today's economy.
3. "The Real Crash" for policy recommendations.
I think the first 2 are better books than the 3rd, because I think Peter Schiff is an incredibly great economic communicator, but only a great policy wonk.
