The german race had indeed a tad of 'superiority' to it. But if you deal with international operating companies, they learn fast to put their ego aside and treat other people as equal.
That being said, german techs are the best around, no doubt about it. Their experience in machine making is unequalled, and their schooling system for training new mechanics is top of the bill.
I have visited several southern US plants in the past and I was shocked many times about low schooled operators who were running expensive equipment. That's why I have difficulty in believing your quality records....but those can be adapted intelligently if you know what i mean.
Production plants in germany however show a high level of "new" immigrants, such as turks, chechs, polish, etc. which are cheaper and less snobby than the average german worker.
Labour cost is killing the european industry ; it will have an impact on our quality in the long run.
