"How can you even claim there are longer wait times when: It reported that in the US a quarter of adults surveyed (26%) said they waited six or more days for primary care appointments "when sick or needing care". The figure for the UK was just 16%."
Because the wait times are longer. This may be the one, cherry-picked datapoint where waits were longer in the US than in a country with socialized healthcare available. And if we were discussion wait times of a week, or two weeks, or even three weeks, I don't think you and I would be having this discussion. Most of my appointments are made two to three weeks out. Not because of the doctor's calendar, but because of mine. It's once you get into the wait times that extend into the years that you really have to admit that it's a systemic problem. particularly when it's present in all the of the socialized systems.
"If its lower quality care and longer wait times then why are ZERO countries trying to copy our health care system? In fact they react to it with a combination of laughter and horror."
Are you kidding?
Canada used to have a single-payer system. If you wanted healthcare in Canada, you had no choice other than the government-managed system. That changed in the mid-2000s after the Canadian Supreme Court determined that the countries long wait times were a violation of the rights of Canadian citizens, as they were forced to go abroad, to somewhere like the US, in order to get timely care. After that ruling, the government was forced to permit private healthcare providers to practice.
In other words, they wanted to become less socialized, and more privatized.
Additionally, most of Europe employs mixed systems. And I don't think you'll ever meet someone from Europe who comes here needing care, and laments that American facilities lack the quality of those in their home countries. I have a few friends from across the pond, and they've all been pretty surprised at the quality of care you receive in the US.
"I pay $15,000 in health insurance. If I added that to my taxes for universal health care I would then be paying ~25% in taxes. so what exactly is your point?"
My point is that if you added that $15k to your tax bill as opposed to paying your insurer, you very may well wind up with lower quality care. To maintain the level of care you have might actually cost you more. If you're committed to the socialized healthcare model, the lower quality care may be acceptable to you. Maybe not. But I think you'd be mistaken to think that a $15K increase in taxes to cover healthcare would not result in a net loss in coverage or quality.
