You guys get the NHS though.
Most Americans get employer-provided health insurance, which costs money (the amount specified in the DD section of the W2), and its often in the $1500/month range. That DD amount isn’t part of your income or the salary Glassdoor mentions. It’s an added benefit of top of that.
In the UK and elsewhere, around $500/month/person in taxes pays for your healthcare. That’s essentially subtracted from your income. So the uk income is even lower when you subtract the taxes the NHS costs.
Nope, but NHS + no/less student loans + no car dependency + cheaper childcare + time off + a ton of other things shave quite a bit off that $200k. Not equal, and not in every personal case, but a lot.
