I mentioned London because it had one of the highest salaries in Europe. I don't have personal experience myself apart from what I saw in Glassdoor.
120k £ (equivalent of $150k at current exchange rate) becomes net 71135 £ which is 61.8%
In the state of New York: https://smartasset.com/taxes/new-york-paycheck-calculator
$150k gets you a take home that is 68% of gross. NYC imposes an additional local tax between 3 and 3.8% so in the worst case you’re still taking home more than 64% of gross.
Maybe the last time you checked $150k was a lot less in £ and therefore taxed at lower rates in the UK?
