This is true, but it's not the best way to make money, and it involves a lot more of pretending you care about others, which will likely get more difficult with time if you actually don't. (=burnout)
I think it's a valid point that this is not the career path to go into if you're set on making a lot of money. Between the changes the government is making and the debt load, there are so many better options. As was said earlier - go into business if you're there for the money. Open a resort - that's kind of like caring for people, without pretending that you're actually doing it with their best interest in mind.
And no, I'm not a naive young student who has never supported myself. I have, and I understand money concerns. I definitely want to be able to pay off my debts, but in my case being realistic also means changing my career because this is what I want to do, regardless of the payoff. Part of that is likely because I come from an exceptionally poor family, so my perspective could just be due to lowered expectations.
Finally, my brain is fried from finals, so thank you for your patience in wading through my awkward sentences.
