Sure. Because they’re doing different work, in proximity to different people and different resources, within different economic contexts. A developer in Silicon Valley is fundamentally more productive than one in London, in part solely by virtue of being in Silicon Valley. (Not true at the individual level, of course. But statistically, of course.)
