Earlier quoted context omitted.
I grew up and lived most of my life in America, then emigrated to a country with universal healthcare (the UK). When I developed a life-threatening condition which my US insurance would never have covered, the National Health Service saved my life. These things don't matter until they really, really, really do. Having seen the grass on both sides of the fence, I can attest that it really can be meaningfully greener.
What life threatening condition did you have that isn't covered by insurance?
In the US, as I say, this would not have been covered by my insurance, and would have cost around $50,000 to fix. Completely infeasible for me to find that amount of money. The NHS did an excellent job of fixing it for free.
