Although it's not nearly as bad as other people have it, even in a good job with good employer-provided healthcare, there are two things that still really bug me about US healthcare. One is a perennial worry that I'll somehow end up with a 6/7-figure bill anyway, for example because I ended up in an ER where some of the doctors were "out of network" (this kind of billing has now been banned in some states, but only a minority of them). If I had no savings I would just not pay the bill, but since I do have some, I worry this could wipe out years of savings overnight, which makes me anxious. The second issue is that it just takes so much time to manage all the bureaucracy. Usually health insurance will in fact pay (if you have a good one), but you can end up spending literally hundreds of hours on the phone, especially if you had the bad fortune to end up in a hospital. In hospitals it seems that every individual person you encounter sends a completely separate bill, half of which the insurance company will initially refuse to pay for various reasons. This can go on for many months after being discharged.
