economic theory used for lug nut manufacturing and distribution to the care of the sick, injured or dying?

It's the same thing. Customer >> product/service.

You want quality medical care from experienced doctors and surgeons, then pay for it. I don't show up to a Ferrari dealership with $20 grand and say give me your fastest. Yet you expect a medical professional inside a completely well equipped medical facility staffed with qualified employees to give you top notch medical care for free? That's crazy.

If you get back surgery for $70 grand, you got a fucking deal.

Think of something simple like a broken arm. The amount of money that goes into that. An xray machine that's radiation won't damage you, but it scans your internal bones and nerves and locates damage. That's in a room specifically outfitted for that one purpose. The guy who does it has a degree and is certified to carry out that task. The engineers who service those machines are also trained and certified and usually hold degrees.

Then a doctor who has 8+ years of higher education who also holds a degree will look at the scan, diagnose the best possible method for treatment, will create a cast CUSTOM fucking fit for your arm to heal in it. Will call you back into his office in a few weeks to check on its progress.

Every time you visit you're blood pressure is checked, your temperature is taken and occasionally a blood sample is taken and also analyzed by a doctor for any protein or chemical deficiency. But all that should be free and they shouldn't make money on any part of that transaction.

Or do you mean instead that someone ELSE should pay your bill for you? Is that what you mean? Because it's a business and their job is to make money by healing and treating your ailments and illnesses and injuries and they should be well compensated because their lives are dedicated to that singular purpose.
