Phosphide, I have to question the thoroughness of your claim about medical bankruptcy. I don't doubt that people who go bankrupt due to health problems often lose their jobs. But you also aren't likely to permanently leave your job because you needed a day or two in the hospital. Losing your job means long term health issues, which in turn means lots of medical care and/or procedures. So even if your job is cool with you being out on medical leave for months at a time, you have another issue here. You're absolutely right that people with insurance go broke paying the out of pocket costs, but that brings us to another huge flaw in our current insurance system...
Note the term I've been using to describe people who are going to have trouble paying their medical bills is "under-insured". I am using that as a catch all for people who have no insurance at all as well as people who have the plans on the most basic end of the ACA mandate. The reason I am using them interchangeably is because we are having a discussion about people needing major attention and lots of work, in which case these basic plans are only a small notch better than having no insurance at all. Obamacare has expanded coverage access to many people, which is a good deal for them if they only need to go for basic checkups with a family doctor and occasionally get some antibiotics for a mild sinus infection. But if you find yourself in need of extensive care from hospital staff and specialists and surgeons, that basic ACA plan is total shit. One really good thing about the ACA is that it makes preventative care a lot easier for people who previously just couldn't go to any doctor until they needed the ER, but in the case of being seriously injured, it leaves you in the same bind.
So unless you're affluent and bought a premium plan, or you're lucky enough to have an employer that offers good coverage, your insurance is gonna let you down when you need it the most. Democrats keep saying that Obamacare is almost where it needs to be and that they just need to apply a couple fixes to expand access to the small percent who aren't yet able to get on a plan. What we're eventually going to have to acknowledge as a country is that Obamacare focused on access instead of cost, meaning that lots of people still can't afford their hospital bills because the affordable, accessible plans that they made available are too cheap to cover serious medical expenses. This leaves us with much of the same dilemma we had before Obamacare: if you're not rich and your employer doesn't voluntarily offer you good insurance, a medical emergency could be financially ruinous to you.
What we need is single payer that provides universal coverage for what is truly reasonable and a medical necessity. Then allow for supplemental plans to cover things that most Americans would want included but could live without. So if you get into a car crash and need surgery plus a 2 weeks recovery time in the hospital, you're not paying your life savings in the out of pocket. If you got a scar on your forehead from the crash and you want a plastic surgeon to put 150 stitches in to make it less noticeable, that's for the supplemental plan. To make this work we also need to try some of the approaches other countries have with regards to things like pharmaceuticals and let's face it, hospitals have legit high overhead costs, but some of the things they charge people for are just gouging, which we'll have to put a stop to if we're serious about this as well.
