Change has not come to the Treasury Department which, like previous Washington administrations, is filled with former Wall Street high flyers. Treasury Secretary Timothy Geithner’s inner circle includes Gene Sperling, who earned more than $1 million last year between working for Goldman Sachs and giving speeches to financial companies. Others include: Lee Sachs, who made more than $3 million from hedge fund Mariner Investment Group; Lewis Alexander, the former chief economist at Citigroup; chief of staff Mark Patterson, who was a lobbyist at Goldman Sachs; and Matthew Kabaker, who worked at private equity firm Blackstone Group LP.
