> Hospitals are for profit corporations. Doctors are reviewed on how much revenue they generate per patient - usually by asking for more diagnosis and treatments - which is what patients want too.

FWIW lots of hospitals are non-profit (though I expect that changes are investors are moving more and more into the space).

That doesn't mean they don't focus on doctor's revenue, it only means there are no owners skimming off the top, but there are still execs being paid (a lot), as well as suppliers, etc... I'm not saying NFP hostpitals are worse (or even as bad as) FP, but they're hardly good.
