While there are many reasons why healthcare cost in America is high...
Start looking at the fact we pay our doctors 3 times more, and medical school education is 6 times more... than Europe.
Have to make the universities ditch all their admin positions and have them run by strictly professors again(something they do not want to do).... and pay our doctors 3 times less(they won't like that, and it will probably cause a shortage in doctors).
We also would have to decrease the service's and the amount of nurses hospitals have.
ALSO have to decrease the wages of lawyers, and medical malpractice insurance... because people have been able to borderline bankrupt hospitals on lawsuits. This opens the whole can of worms on how are legal structure is and the amount of regulations that is making the legal structure extremely expensive(Something the fat democrat law firms don't want to give up)
America's Healthcare is the most expensive, but it is the best healthcare. We have the best medical technology and doctors by far.... even though not everyone gets access to the best of course..... because it's expensive.
I hope you understand.... It is not so simple as let's "Just make Universal healthcare', and it isn't expensive BECAUSE it's private. It's actually expensive because of government subsidized medical education, Lawyer lobbyists, a regulation bloat that increased the amount of required positions for administration.
You are absolutely correct that medical school IS expensive and the cost of healthcare can be expensive when you go to the doctor's office. However, no one has been asking doctors or healthcare practices (in particular small businesses) as to why costs are high. I work at a small business doctor's office, and there are 2 factors to answer that question.
First off, the government. Medicare, and Medicaid in particular. All of our coding has to be compatible with what both of those government programs want. Both pay doctors and their staff next to nothing. I know this because we are one of the only healthcare providers in town, in our field (the ophthalmic field), that take both, which includes the baggage of all their supplements. Through Medicaid, for glasses, we're talking about getting paid between $15-$25. Exams, pretty close to the same amount. Medicare pay us a little better on exams, but do nothing on glasses nor refractions, unless you have cataract surgery one time but the benefits are so small, you may as well pay cash. The doctor I work for is an O.D. so he can do medical procedures and prescribe medications. The medical aspect of Medicare, however, isn't good. They rarely pay for procedures and they tag on new regulations to make it harder. That's why the greatest problem with our healthcare system is the government.
Second, the insurance companies. These are almost as bad as the government. They are one of the main reasons a doctor's visit is expensive. They pay less than half of what we're owed, throw on new regulations, and many of them are in bed with the government. Paramount Health, United Healthcare, Molina, even some vision insurance companies like Vision Service Plan (VSP) and Eyemed all have a form of Medicaid plan, so we know they're sleeping with the government. Eyemed is a good example of how bad insurance companies are: We bill out $130 to the insurance. The patient has a $10 copay, so it knocks down the bill to $120 for the insurance. They don't pay the rest of the $120. You would think "okay, well they'll pay us 75% of that amount so it's fine." You would be wrong. "60%" you would ask. Nope. "How about 50%?" Closer but no. "What percentage would the pay?" Around 40%, which is converted closer to $45-$48. Glasses are not much better. $200 we bill to the insurance and we get paid $80. Does that even sound fair?
How do we solve these 2 problems? First, people need to recognize that insurance does NOT provide healthcare. Doctors and other health practitioners do. Second, if you pay cash with no insurance, offices will lower prices because they want to compete. Third, get the government out of our system. I can't stress that enough. Fourth, tax reductions are crucial because state colleges that have medical schools cost an arm and leg, but when taxes go down, tuition will go down and debt will not be as great. And don't be fooled by others. Professors that work at state colleges are working for the state, and that's why they want higher taxes (that's how they get paid). Fifth, if you have health insurance, only use it when you absolutely need it. If your bill is $50, just go ahead and pay that amount in full and save your insurance for later, for something far more expensive. There are other factors, but do these steps and many problems will be solved. Medicare for all will only make things worse for both doctors and their patients ($30 trillion isn't flattering).
