Imagine for a minute that everyone had BASIC health insurance. Provided by the government. If they get cancer, it will be paid for. If they sneeze, they will pay out-of-pocket for a doctor. Doctors who are AMAZING will charge... 200 for a visit. Not so amazing ones... 30.
Woah there. If your doctor charges you 150 per visit, you will be sure as hell checking that the doctor is good. While at $30 whatever. If you pay for your drugs, you will be damn sure you need them at $150 a pop. But at $15 a pop, meh better be safe than sorry.
Now an insurance company comes along... Hold up, sure I'll pay for it but how easy is it to make claims? Are they actually paying out or are they just giving you red tape?
It goes on.
Look at the COMPETITION created:
Doctors compete on skill to get not only clients who pay next to nothing per visit but pay hundreds to the doctor, but also on how much they charge.
Treatments compete on effectiveness. Will I pay $10k for a treatment that may be equally as effective as a $1k treatment?
Insurance companies compete on coverage/serving customers. Because anyone can leave and switch, and if they don't they have the safety net. Insurance companies now stop having the per-person monopoly. Very rarely do people have any choice in insurance companies.
Employers have employees who have only the risk of lack of salary when leaving a job. Though that risk is bad, especially when owning a mortgage.
The competition created becomes crazy. Entire monopolistic business models get toppled. And all for a very very small price. The fun part is once the free market kicks in, prices will plumet too. Competition will ensure to that. We just have to make sure competition gets a chance.
