World Of Trouble

(CBS) How did the mortgage industry destroy itself and set off an economic collapse that ruined the finances of millions of Americans? Executives tend to hold themselves blameless, saying that no one could have seen the disaster coming.

Well, judge for yourself after you hear the story of Paul Bishop, who worked at the nation's second largest savings and loan. World Savings Bank was among the industry's most admired mortgage lenders. But Bishop says the kind of lending practices he saw were leading to a world of trouble that would ultimately result in billions in losses and a federal investigation.

What does Paul Bishop say he told executives at World Savings, three years before the crash?

"We're breaking the law, okay? We're breaking the law. You know we're breaking the law. I know we're breaking the law. What the hell do you think is going on here? You know, you're granting too many people loans who simply can't qualify," Bishop told 60 Minutes correspondent Scott Pelley.
