The question is what you are angling for. If your goal is, sincerely, to provide better service, then you won't get it. Keep in mind that with so many patients nowadays being eligible for Medicare, the money will come in anyway. Nursing homes got the brunt of the attention for their quality of care, but with hospitals facing the same population the same management techniques come too.

I work as a nurse on nights and everything said above has been quite accurate. A textbook understanding of... well anything really, does not serve someone well now.

EDIT: Also these companies now often run pharmacies, investment systems, healthcare programs... patient care is by no means the biggest earner.
