Today the jury decided that O-J Simpson must pay $25-million dollars in compensatory damages for the deaths of Nicole Brown Simpson and Ronald Goldman. In most basic terms, they decided what amount of money equals Simpson's crime. We've been making comparisons like this for thousands of years, according to Jack Weatherford, who sees bad and good in the process. Weatherford teaches anthropology at Macalester College in Saint Paul, and his latest book is "The History of Money." Minnesota Public Radio's John Rabe and senior economics editor Chris Farrell talked with Weatherford about his book, which starts in the kingdom of Lydia somewhere around 635-B.C.
