76k gross per year in Germany is basically the same as that. 100k gross comes out to about 5.5k net per month. The big question is how much is already covered once you're down to the net pay.
I'm not sure of the situation for software engineers but ones on the aerospace and mechanical side working in aerospace in Europe are paid something on the order of 50% less than ones in the US. I always assumed it's just a supply demand problem but I haven't run the numbers.
If you want to go further into bringing other stuff in I would say, on average, the European folks are only slightly worse off money wise (owning a house there does seem harder overall) but with more security, time off, etc.
In the US there is a much broader range of experiences in the sector, partly because of personal circumstances (student and auto loans being the biggest) and alot because of where you live, as pay tends not to scale with COL. So someone could live like a king in rural Iowa or a pauper in Los Angeles doing the same job.
