With regards to for-profit medicine, this is why I hate all market based health insurance systems. Even if you are rich and get treated like a king, you still have to question whether your doctor/surgeon is trying to sell you a procedure. The only system that does not suffer from this issue is the NHS (e.g. UK) where the incentive is lacking. The debate about health care systems tends to focus on availability and coverage, but this for-profit perverse incentive is orthogonal to all that.
