Just finished reading the book by Amity Schlaes. Very interesting & a good read.
Grew up on a hardscrabble Vermont farm in the late 1800's. Not unusual as the majority of the US population was living on the farm. Family was political, Dad was a VT state senator. Good read while somewhat detailed on occasion. Will not say what was in the book though there was one glaring error, which you will have to find on your own.
He did manage to bring the national debt under 20 Billion$ with a budget just over 3 billion$ . I won't describe what I took from the book until others who choose to do so have read it & are prepared to discuss his legacy.
