Joe Biden's next gig could be on Wall Street

Joe Biden joked that he might want a job with Wall Street giant Goldman Sachs after his term is up this time next year. The vice president was speaking at a dinner hosted by the bank in advance of the World Economic Forum in Davos, Switzerland on Wednesday.

"I’m not qualified, but I may be coming back to you," he said to Goldman representatives at the event, adding that he has "never been gainfully employed before."

While Biden may have only been kidding, Goldman in particular is emblematic of the "revolving door" between Wall Street and the federal government, frequently serving as a destination for former federal officials and a hiring pool for new ones. Former Presidents Bill Clinton and George W. Bush both picked treasury secretaries from the bank's ranks, and Goldman was also the source of several lesser-known Obama appointees.
