Medicine as a profit center

Are pharmaceutical drugs in the business of making profits? Sure they are, and I am of the belief that prevention is the key to beating disease (based quite a bit on nutrition), although the "we have a pill for everything" mindset makes for a profitable enterprise in this day and age.

How about actual medical complexes? Hospitals and doctors are not in the business to operate as break-even or a loss either. Although many a doctor loves what they do regardless of money, I suspect that millions of procedures are done for profit motives other than "best for the patient" motives -- but that's just me. How about you?
