Historically, the money in London has always been in the finance sector. Both large banks and hedge funds.

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.

That seems about right. 100-200k GBP in London, 200k-400k USD in the USA. Standard packages for people with a few years of experience.
