He has a severe chronic condition.
Health insurance for him as a self employed person at the time was $4k/month
Tuition at the local public college at the time came with a senior discount for folks in his age group and insurance for $10k/year.
He loved the classes and saved a bundle on health insurance.
He needed a life flight and weeks of hospitalization related to his chronic illness. The insurance had him covered. I think it was a non-trivial payout for the insurance company.
The following year the insurance company changed the terms with the university to charge more if you didn’t live on campus.
My father went to a different school with a different insurer after that.
He’s finally on Medicare.
We shouldn’t tie healthcare coverage to employment in our country.
It’s stupidly expensive.
