I've seen mid-level tech jobs in London banks for £146k which come with 34 days off including state holidays like new years day, christmas, etc
£146k for a full time contractor on 226 days a year isn't that much at all - £650 a day, which is in the "Senior developer" range [0]
With 30% tax in the US and the cost of health insurance, that would be $68,400
For a staff employee on £146k (which is quite achievable in finance), taxes would be 39.5%, or $79k in tax [1] (there's also local property tax, but that's in the ballpark £1k-3k a year depending on the size of your house). Tax could be potentially lower as a contractor if you're clever about distributing your income, but I know they've been clamping down on some avoidance schemes.
No idea what a HSA account is, I guess some form of pension plan? That tends to come off pre-tax.
