Im 41 and haven't been to a doctor since I was 10. I have had insurance coverage my whole life. So technically I (my employer on my behalf I guess) have paid for many other people's services.
I have been a huge net positive for insurance companies. Other people get way more services than they ever paid.
Nobody in my family has any kind of crazy chronic conditions. A few surgeries, a couple of c-sections, a week in the NICU, a few short stays in some hospitals. We've experienced nearly half a million in healthcare benefits from our insurance companies over the years. I don't think I'm ever going to pay enough in premiums to cover these costs.
