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.
