Well, when you have 40k in debt from student loans, etc and are trying to make it in this over priced world, and you come from a family that is middle class with 4 kids, money surely is a motivator. When you want security for the rest of your life, I'd also say, seeing my mom struggle her whole life with finances, money is a motivator. It does help that I'm compassionate tho, I'm sure some in the field aren't suited for the job, but money is a definite motivator for me (and job security).
