Genuine question, have you considered giving in and going to work in the USA? As an American, working as a software consultant in the UK is swimming against the tide. You could be free of the tax burden and earn more by working practically anywhere in the USA.

I know money isn't everything, but would be curious to know what is keeping you in London (as someone in an analogous situation asking myself the same question).

My wife is British, and my kids are thoroughly integrated with the local community. So that's what keeps me here. If I was single I'd definitely go back at this point, it's too much of a headache, and my earning potential would be way higher in the USA like you say.
