What's your opinion of people who are only in it for the money, after a certain point in their career?

Like some people IRL i've talked too keep saying "the only people who are making the big bucks are the ones who are really passionate. If they didn't love IT they wouldn't be that far and wouldn't be making that much."

What do you all think of this? Is passion really that important for your experience? How many of your supervisors and managers (I'm talking about the ones who are competent and not morons) do you think got their position because of passion and love?

Are you a person who says "Fuck passion, this is a job that pays the bills, and I'm reasonably competent, all that other stuff is just extra."
