It's really just mental healthcare and dentistry that are basically impossible, but again, not much better with a private health plan.
Take the blinders off, stop pretending you're not getting robbed, and maybe we can fix it. There is no silver lining to private healthcare. You're not getting better care. Social determinants of health are very real, but they're driven by those 9 states without Medicaid expansion dragging the averages way down, a lifetime of bad care before the ACA, and also that medicine can't solve the many problems caused by poverty.
We would all be better off in literally any other system. Everyone thinks they're an above average driver. Everyone thinks they'll live longer than average. The truth is, you're just not that special. Unless you're a politician that gets to go to Walter Reed, or you have a wing in the hospital named after you, you're getting the abysmal standard of care that everyone gets.
