IME salaries have risen fairly significantly in London over the past 7 years or so, up until about 2 years ago.

I don't think dev immigration has hurt that much if at all. There's a virtuous circle: the more devs there are, the more startups are created and the more FAANGs set up shop. Devs get more experienced on bigger and harder problems, which makes them more valuable.

There's a huge amount of developer immigration to SV, and yet that's where the highest salaries are. Would they really be even higher if FB, Google, Apple etc. couldn't find enough devs to hire, or would those companies have set up shop in other areas and countries instead, to accommodate their needs? Or would those companies have been growth constrained on availability of talent instead?
