Let’s say you own a burger restaurant. You serve a couple hundred paying customers a day and make a nice living. But then one day a law was passed that you had to give a free burger and fries to every homeless person that walked in the door.
How would you feel?
Now let’s say you own a Mercedes dealership. You now have to give a $80,000 car to every homeless person that walks in.
How does that one feel?
How would you keep your head above water?
That is a bad analogy. A doctor provides a service not sell a product.
It's actually the hospital we are talking about here, not the doctor. They invest in a multimillion dollar machine that helps diagnose illness. Then they pay high salaries to doctors and nurses for their expertise and training. In order to recoup these investments, they charge the patients that use them. But something like 25-30% of the patients they treat are indigents that pay nothing.
Look, I'm not saying its fair. But the reality is you cannot half regulate. You can't have a for profit system and not allow the market to regulate itself.
A fully capitalistic medical system would provide the absolute best medical care. But it would require some people to not have access to it.
A state funded medical system would provide full medical care to all, but because you are taking the incentive for profit out of the equation the quality of care diminishes.
Sure the UK has universal healthcare to all. But their level of healthcare is basically go to a clinic and get a prescription for an antibiotic and an aspirin. Getting an MRI to diagnose an underlying problem is a 6-month process. People in England with the means to do so come here for medical treatment, as do Canada.
