A Brief History of British Rails, the recruiters perspective:
Louis Goff-Beardsley

It amazes me how cheap senior devs are in London. I don’t know how you can live decently on £60k in London. Obviously £80k is better, but I doubt you living the high life on that salary in London. Here in the US senior RoR devs are £100k+-ish.
I also think a lot of the foreign devs probably go to Germany now instead of UK as I hear the salaries are higher there.
