Kevin Sullivan and Mary Jordan:

Carter decided that his income would come from writing, and he has written 33 books, about his life and career, his faith, Middle East peace, women’s rights, aging, fishing, woodworking, even a children’s book written with his daughter, Amy Carter, called “The Little Baby Snoogle-Fleejer.”

With book income and the $210,700 annual pension all former presidents receive, the Carters live comfortably. But his books have never fetched the massive sums commanded by more recent presidents.

Carter has been an ex-president for 37 years, longer than anyone else in history. His simple lifestyle is increasingly rare in this era of President Trump, a billionaire with gold-plated sinks in his private jet, Manhattan penthouse and Mar-a-Lago estate.

Carter is the only president in the modern era to return full-time to the house he lived in before he entered politics — a two-bedroom rancher assessed at $167,000, less than the value of the armored Secret Service vehicles parked outside.
