5. The United States borrows a lot of money but is a young country, 240 year-old compared to England which is over 1,000 years old and China which is over 5,000 years old. In our life cycle consumption hypothesis young people borrow more to get started and then pay it back in middle-age. There are differences between people who have an expected life span and such and countries which may last a very long time but is there a parallel here? Is The US just a young country borrowing in its early years?
