Maybe! Not sure I've seen data that supports that, but it's a sound hypothesis among some populations. That said, the students who do the very least work and learn absolutely nothing are the ones too poor to ever become undergraduate students in the first place ;)
I see it all the time. Money is a very effective motivator. Working to get money is very much going to influence what you choose to buy with it - and you're going to want to get your money's worth.
Money is an effective motivator until it isn't. I quit an extremely lucrative job because I hated the person I was turning in to and haven't looked back.
I would be wary of making generalizations on motivation which is highly variable person to person.
I neither wrote nor implied that money is the sole motivator of people. There are many things I won't do for money. For example, I won't engage in the lucrative business of drug dealing. That doesn't imply that money doesn't motivate me.
I bet you still do things for money, even if you'd rather have fun instead.
