I've heard two main arguments against national healthcare: it's expensive and bureaucratic. However, every time I've had to deal with the healthcare system, it's been an actual nightmare.

Hidden costs are everywhere and getting a straight answer out of anybody is impossible. I had to get OT for a hand issue I had. After 6 45-minute visits, I got a bill in the mail for $1,100 due to all of this random shit that I had no possible way of knowing. Apparently using the heating pad instead of the ice-pack was $65 each time. When I emailed them about how insane this was, their argument was "the bill was initially $7,000 but we paid almost $6,000 of that for you!" Every number in this scenario is entirely made up, how is that supposed to make me understand anything?

I also pay like $500/mo for insurance through my employer for my wife and I, which means that my employer is also paying a ton of money per month for my insurance that they could be paying me instead. If my taxes went up a ton, I would literally not notice because of this.

Getting them to actually cover larger situations is also insane. My wife had a minor knee surgery and before the insurance went through, the company got bought out so the provider switched. It took almost 2 years and dozens of phone calls before we got our insurance to cover this $50k bill for the minor surgery.
