But in this book he's saying (over and again) not much more than:
1. Empires are created by vainglorious self-deluded fools. 2. Empires always overreach and go broke and collapse. 3. America is an Empire. 4. America buys more from overseas than it sells there, and that's bad. 5. Americans spend too much and don't save enough. 6. The housing market is a bubble due to pop. 7. Gold is a good store of value.
That's about it, along with some fragments of schoolbook history. Hope I "saved" you some money!
