I think even in finance you'll be unlikely to touch 400USD (~300 GBP) for a similar level. Sure there are outliers, but of the senior people I know in this area

I think even in finance you'll be unlikely to touch 400USD (~300 GBP) for a similar level. Sure there are outliers, but of the senior people I know in this area total comp is around 200GBP after many years. It's much easier to just contract (if you don't mind the mercenary role), you'll make similar due to the tax savings.
