Kevin Delaney has had money on the brain since he was a little kid.
Growing up in a large, working class family of seven, money was always tight. He remembers watching his father work multiple jobs and count out the cash he earned on the kitchen table dollar by dollar.
Since then, Delaney has handled money as a bartender, toll booth operator, but these days, he's a professor of sociology at Temple University.
He's written a new book called "Money at Work: On the Job with Priests, Poker Players and Hedge Fund Traders." It looks at how the work we do influences our thoughts on the value of money.
