One memory particularly troubles Theckston (Nota: el banquero, ex-regional vice president for Chase Home Finance in southern Florida). He says that some account executives earned a commission seven times higher from subprime loans, rather than prime mortgages. So they looked for less savvy borrowers — those with less education, without previous mortgage experience, or without fluent English — and nudged them toward subprime loans.

Theckston, who has a shelf full of awards that he won from Chase, such as “sales manager of the year,” showed me his 2006 performance review. It indicates that 60 percent of his evaluation depended on him increasing high-risk loans.
