Like another poster said, the great health benefits are in state/fed/municipal jobs that are paid by taxpayers, along with a strong union that protects the workers regardless of whether the workplace has any money. I worked in a place like that (as a benefitless part-timer) and the full-timers used every ounce of that cadalliac insurance to the max (I never met so many people with so many specialist for every body part). I was just let go (along with 5 others) so the workplace could continue to pay the cadalliac benefits to the full-timers.
So that's where the best insurance is - in jobs where the taxpayer pays for it.
