In Cheap We Trust: The Story of a Misunderstood American Virtue by Lauren Weber
This book delves into America's history of spending and saving (personal, not governmental). You might be surprised to find that many of our forefathers were not exactly bastions of thrift (as most of us have probably been led to believe) and that certain immigrant groups were chastised severely for their saving habits. The author also throws in stories of her own frugal upbringing and explains why she thinks thrift should be embraced by modern society.
I thought it was an enjoyable read.
