Yeah, I think that a lot of health care jobs are safe from this down turn (at least when you look at clinical jobs). People are still going to be getting sick, and they still need people to take care of them. With that being said, however, we are fully staffed where I work (in RT). We actually have several part time people that want to come to full time, but we don't have the positions for them.
There is such a shortage of anesthesia providers, though, I don't see there being a down turn in job openings anytime soon... the bigger question will be reimbursement.
That is my opinion, at least. I sure hope these salaries stay up for another 40 years... not looking into this field for the money, but it sure is a nice perk!
