> If there were 100 qualified surgeons for every patient needing an operation, and would stampede each other for a chance to work and get paid, we'd pay them $25/hour too.
Given how opaque the healthcare industry is when it comes to cost for non elective surgeries, I doubt costs would go down even if you multiplied the number of surgeons by 1000. Case points: there are loads of restaurants yet the hospital will steal bill a meal 20 times what it would cost in the nearby restaurant.
