the IT wages in Germany aren't as high, you're looking at €3000-€5000 above your typical factory worker for the type of work they seem to be looking for, BUT therefor they also have German levels of workers right XD, just wait 5 years when Google decides to outsource somewhere else again, and realizes it can't afford to pay the severance of all those employees
IT wages may not be as high in Germany as in Silicon Valley (cost of living is also a lot lower), but they are certainly a far cry from "cheap." Also, German workers have much, much better labor conditions overall than US workers. They aren't easy to cast aside like Google has a habit of doing.
