Two years ago, the PBS show FRONTLINE^® did a report called Secret History of the Credit Card. The video and transcript are online. It is an excellent starting point for the March 2007 topic.

In “Secret History of the Credit Card,” FRONTLINE^® and The New York Times join forces to investigate an industry few Americans fully understand. In this one-hour report, correspondent Lowell Bergman uncovers the techniques used by the industry to earn record profits and get consumers to take on more debt.

“The almost magical convenience of plastic money is critical to our famously compulsive consumer economy,” Bergman says. “With more than 641 million credit cards in circulation and accounting for an estimated $1.5 trillion of consumer spending, the U.S. economy has clearly gone plastic.”

Millions of American families use their personal, general-purpose credit cards such as Visa, Mastercard, American Express and Discover to make ends meet; credit cards have been a discreet lifeline for families in financial straits.
