Having been in hospital in the UK NHS for three weeks before Xmas last year, for a painful condition that needed constant dressings and attention, I can only say that you can't possibly pay nurses too much.

NHS nurses (and junior doctors) pay is disgustingly much lower than in the USA.

The only reason healthcare professionals in the US can demand salaries this high and even higher is because supply is artificially constrained. There are many qualified prospective students adept, intelligent, studious, and diligent enough that they would join the healthcare field were it not for the financial barriers, hazing-like process, and unnecessary performative work you have to get through to even be admitted to a school. Because of the undergraduate/professional school tiering system, many pre-health students choose majors that don't help them at all in the event that they decide to give up their professional degree midway or change directions, making it particularly ruinous financially and career-wise.

They work insane hours caring for people living in NYC, of course they do!
