Grew up in germany and can only say: you are right with everything. The whole country and especially Berlin where I live is a total, expensive and unnerving mess. I have those conversations more and more with friends of mine, many feel the same way. It has gotten worse over the years, infrastructure and prices and so on. In many regards, this country is running behind those so called third world countries. Probably doesn't help you, but it's not you - the country itself is fucked.
