Will Nursing always be HOT?

So, I've heard the "saying" before that in the context of careers, "whatever is hot now, will not be in the future".

1. Nursing Shortage
We talk about nurses shortage all the time nowadays, so would it be imaginable, that because of this shortage, we have so many people right now going into nursing that there won't be a shortage in the future?

2. Nursing Profession
So I've read quite a few messages posted on this board, and so I get the feeling that the Nursing profession or at least the environment has changed quite a bit from a couple years before. Changes in that healtcare/hospitals has turned into a big business not longer caring as much about the patient as before. Do you think this will improve in the future?
I want to leave the "corporate world" to become a nurse, so I would really hate it if I find myself in the same environment.
