Developer salaries in Europe are ridiculously bad, not sure about Paris specifically, but one of my in-laws moved from Vienna to San Francisco and the salary boost was ridiculous (and housing in Vienna proper is extremely expensive too, so it's not as if he moved from a cheap country). We've had developers move from Spain to Chile, and even Uruguay where I am, rather than France, so there must be some problem with salaries (they do have the advantage of the same language here of course).
