I can feel you. I had exactly the same feeling when working for a big german cooperation. However let me tell you that the grass is not necessarily greener elsewhere. One thing you mention is domain knowledge. This actually also a big problem in the US tech companies. The people fluctuation is so high that after some years nobody might really know anymore how a certain component works. This is not that much of a problem in german companies. Also the bigger german cooperations have I'm aware of had better planning, project management and QA than things projects I witnessed elsewhere (sample size is obviously limited). While that sounds like more bureaucratic effort, it still reduces the chaotic aspects in projects and improves the chance they will finish on time.
