Take the NHS in the United Kingdom.
For my high wage, my NHS fee would be just under £7k for the year, my taxes just about at 30%.
Granted here in the US, my taxes are ONLY 25%, but my healthcare costs are close to $30k/year.
That $20k difference is ridiculous ($11k more than in the UK when comparing tax+health), and I HAVEN'T gone to the hospital for a heart attack or premature baby or hemophilia, but if my wife did have a baby, it would cost us out of pocket around $8k (according to the likely VERY skewed numbers in my insurance packet).
A colleague I know is 54, he is single, has only catastrophic coverage and pays $1200/mo. Nothing is covered except 40% of any emergency hospitalizations. The bronze plan was $2000 and had a $15k deductible, and also was basically only co-insurance with $30 generics.
The way we are doing this here in the US is literally killing people. Medical debt is increasing.
My little sister-in-law was on vacation and walking along a path on a jetty with handrails, and benches, and dozens of other people. A rogue wave came and hit her and her friend. She was taken under, knocked unconscious and drowned (and died), until a random stranger who was standing near her finally found her and resuscitated her. She was medivaced to a hospital by helicopter that insurance only covered 10% of because she was out of network, she was then treated by a dozen or so doctors for multiple days as she got pneumonia and broken bones, and head trauma, all out of network. She ended up owing close to $100k with her insurance only covering the first $25k. In any other first-world country, she'd be out of pocket maybe a few hundred bucks. Not in collections for being unable to pay $75k for a freak accident.
