The thing is in the US, generally the more you make the lower your insurance costs are.

I made ~$300k last year at a FAANG (Sr. engineer), and my healthcare costs were:

$29/month in premiums $200/month in an HSA, which I'm saving for retirement (complicated US income tax reasons), so money I don't available for my use but it doesn't go into a black hole either. $1500 deducible $3000 total out of pocket

I had a sudden health condition last year, before covid fortunatly, so I maxed out my insurance. So my total costs ended up being $3348 + HSA contributions.

I'm in Washington State, so there's no state income tax, my effective federal tax rate will probably be about 27%.

I'd love to Europe, but it's hard looking at the numbers to justify it. Even if I were willing to take a 50% cut in take home pay, I doubt I could find a job that paid that much.
