Because the federal system has a strong bias towards states as opposed to people, you need to change the minds of people in the resource extraction states.
Is there? One obvious question would be how such polls are worded. I'm sure you can get 60% of americans to agree on "universal healthcare", but only 25% agree with universal healthcare proposal A, and 35% agree with universal healthcare proposal B. In the end there isn't enough support for a specific proposal, because it means different things to different people. We saw that with brexit, where the majority voted "leave", but they all had different ideas of what "leave" meant, and none of the concrete proposals had anywhere near 50% approval rating.
IDK why this happened, though. WTF "loves" their insurance provider?
Why Biden got the nod is somewhat beyond me. My best guess is that most of the democrats in the primaries figured he was less scary than a socialist for middle of the road voters.
I think this boils down to propaganda. Americans have been taught that the "competitive" private insurance system gives them "choice", even though in reality they have maybe one or three plans from their employer that they can choose from, assuming they are working for an employer that gives them health benefits.
The ACA marketplace does seem to give people choice, though decent, low-deductible plans are pretty expensive and are likely out of reach for most people who get their insurance that way.
The other rationalization -- which I am somewhat sympathetic toward -- is that people don't trust the government to do a good job providing health coverage. They believe it will be riddled with red tape and inefficiencies and bureaucracy, and will cost much more than the private insurance system. And that's even before we get to the "death panels" FUD and other invented nonsense.
This is really something that I wish more Americans could just experience.
I've had the fortune (mis?) to experience England's NHS system.
England isn't particularly known for running a bureaucracy free government :D. Yet, the NHS feels like a dream compared to the US healthcare system. I pretty much just filled out a card saying where I lived and that was it. Really bizarre for a non-UK or EU citizen.
After that, no bill, no nothing. IDK if I even needed to fill out the card TBH. Doctors appointments were just like you'd do with a regular doctor in the US. Simply schedule and show up.
A friend needed surgery while there and again, pretty much the same thing, showed up to the emergency room and got seen almost immediately.
All in all, wasn't really any worse than what I'd get in any US hospital.
We see so much paperwork in the US because there are (at least) 3 parties involved in every medical bill. You, your insurance, and the hospital.
Single payer cuts your involvement to 0 which kills pretty much all your paperwork. It also vastly simplifies hospital billing.
It's the technical equivalent to supporting 100s of standards and then dropping down to a single standard. Even if that standard is garbage, eliminates the need to support the 99 standards (even if some are better).
Costwise, it can't help but be less. The fact is, there's a lot of duplicate jobs in each insurance agency as well as some jobs that simply won't exist (no need for accuracy tables, for example).
To speak more generally about means testing, you seem to think that reasonable people oppose means testing because it affects the well-to-do. That isn't the case. The well-to-do have little problem filling out forms or hiring experts in form-filling. Reasonable people oppose means testing because those who can't complete the various clerical tasks entailed are precisely those who need the benefits. And of course the administration of means testing is complicated enough that its costs usually rival those of the benefit programs themselves.
To give an example, some years ago my father helped my grandmother apply to EEOICP, because my grandfather had died with cancer and he had been involved with unsafe incidents while in the employ of the Atomic Energy Commission. We would have been challenged to do it ourselves, but my father located an agent who specialized in such applications. Previously my grandmother didn't know that the program existed, and certainly didn't know the first thing about applying to it. That means that many other AEC widows, who didn't have people around who could help, did not receive the benefits supposedly designated for them. USA has lots of means-tested benefits that serve small fractions of the populations they are marketed to serve. This is by design. The concept of means testing is a story told to make benefit programs less effective.
Even for a healthy child, you need to go through the humiliating experience of weighing your child at a social services office to prove that you are feeding it, for example. Failure to appear can impact your benefits.
I was glad I had paperwork that outlined my daughter's diagnosis, but it didn't matter.
During the Medicaid application, it asked for a signature to collect medical records on my behalf from the hospital. I signed both, and returned them in our application.
Of four, one of the reasons we were denied Medicaid is because they claim I never signed the paper (or returned, I forget), which was incorrect (I have proof), so they weren't able to collect Medical records. During my hearing, the State weren't able to provide any proof that I didn't sign/return, so it was unfounded, but it didn't change anything, nor did I get an apology.
There were multiple ways to qualify for Medicaid and some of them are purely based on poverty with no disability or medical issues. Those cases needed the carefully documented income, bank accounts, retirement funds, etc. It's a bad system in many ways in and of itself, but at a high level they do need some way to confirm that Elon Musk isn't applying for Medicaid just for shits and giggles.
The other qualifiers for Medicaid are medical issues that are detached from income.
The frustration of it all is that there is a single form and while you'd hope there'd be a 'skip this section if you do not qualify based on income' there isn't, and you can end up trying to pull together every financial document you have.
( It can be worth a try to attach a W-2 so they have something and stopping there. They can contact you if they need more )
A better system would provide healthcare to everyone and just tax Musk more to pay for it.
I mean, who cares if he is if it means people like this are able to get the care that they need? That would be such a small drop in the bucket compared to all the people who genuinely have been screwed by the system.
If Elon Musk uses $2.5 million in healthcare but pays 200x or more than that in taxes I don't see that as a problem.
