13. Marion and Herb Sandler
This shady couple founded Sanders’ World Savings Bank and they were the first to sell tricky home loans called the option ARM. For over two decades, they misled borrowers with options to back-load their loans and reduce early payments, which ended with the couple walking away with $2.3 billion after they sold their bank to Wachovia. Unfortunately, Wachovia also inherited their loan portfolio, which sank the bank in 2006. Of course, the Sandlers believe they are not the ones to blame.
