I agree.
When I left my job as a games developer for a gig in the City my salary doubled.
I had zero experience in financial software and about 5 years as a professional game developer.
In that year I was the third developer leaving that studio for the City.
The work was less interesting, but I went from living like a student to having enough income to live independently in London while saving enough to start my own business.
The only software jobs in the UK that approach the US in salary terms are in the City.

You can find considerably more interesting contract work outside the City that pays the same as a salaried role in the City - worth considering if you don't mind a little uncertainty, don't want to work overtime, and want to be able to switch around whenever things get dull...
