Moving to non-profit insurance will not solve the problem, as insurance is only one piece. Many insurance companies are making far less under the ACA than pre-ACA. The problem, is we try and have a market based health system in a globalized health system that is not market based. Particularly, pharmaceutical, durable medical equipment, etc. We pay many times more for drugs, diagnostics, imaging, etc. than any other industrialized country. I posted information a year or two ago that shows that while our government and our citizens pay more than every other country for care, we go to the Dr. and hospital less often.
Why is this? Simple. Most industrialized countries cap what medical companies can be reimbursed/paid for their drugs/equipment. So a pill in Canada may cost $1 and it could cost $50 in America. We are the only industrialized country that does not have serious pay caps of some sort in place. Essentially, we are allowing all of these medical companies to make a profit. The U.S. has 4-5% of the worlds population but provides for something like 70% of profits for pharmaceutical companies. I am all for a free market economy, but in a global market, where we are the only one doing it, it simply does not work.
So all of these comparisons that other countries get the same or better care for lower cost is created by this unbalanced system. The U.S. needs to put similar cost controls in place, which may result in loss in innovation, or lack of availability of drugs and services (if a pharmaceutical company can't make money on a drug, they'll stop making it). This will ultimately result in other countries having to raise their caps to continue to receive the same services. It is time for the U.S. to stop subsidizing the world health market.
And while the ACA may be "dismantled", Trump wants to keep some of the most problematic pieces. If you can't exclude coverage for a pre-existing condition, why would I pay for insurance before I get sick? If I can get insurance on my home after my house burns down, that is what I will do. I understand the thought behind it, but it turns cost-sharing (insurance) into a redistribution of wealth from the middle class to the poor.
Honestly, I'd love the U.S. to go to a single payer system. Our costs will drop, and the rest of the worlds will go up.
