First of all, you have to adjust this for the cost of living and the fact that employers have to pay about half of the health insurance and retirement savings cost on top of the salary as well as three or four weeks of payed holidays etc. 55k Euros in Munich is easily worth more than $100k in the US.

Second, a CS graduate can certainly get 60k in Munich and a PhD will likely have 70k or more. At BMW this may be 80k or more.
