I'm Dutch, an additional 5k per month would not buy me the feeling of safety I enjoy in the Netherlands. It's not just medical bills. It's also the crime and rape rates. You don't cover death and trauma with insurance.
But I encountered a funny additional problem with that recently when talking to a European transplant which is: you need a car in the US. The US is huge and cheap and safe but you need a car. If you don't have a car you have to live within a subway system. Then it's not cheap/safe (pick one).
As a result, check your position in the happiness index and wonder if you, as a country, maybe fail your citizens. The only index where the US is leading is GDP, and that’s not a big factor in anyone’s life.
You can’t put a price on feeling safe. There are lots of tiktok and yt videos of expats living here who explain just that.
