He says he's "in it for the money" because he's honest. No one working to earn a living is not in it for the money, and if they tell you otherwise they're delusional. I think the measure should be "Would you still program if this wasn't your job?" and if the answer is yes, then the passion is there.
I really hate it when people decry the importance of money, because money is basically our unit of human sustenance. It is what we trade for food, shelter, and clothing.
