I could agree if you're referring to low skill or some entry level jobs. For later professional jobs, this may be true for some, but a lot of people really do have professional career interests, and all things being equal, it's normal for an employer to prefer people who want to be there for more than a paycheck.

I've had a few glimpses of what it's like to hate your job and just be there because you need or want the money, and personally, I'm motivated by never wanting to be in that position.
