That is a very good point. Their intellectual property development is absolutely top notch.
Some of their manufacturing/production machinery can not be matched, and the only place you can get it is from German companies, based in and made in Germany.
There are just certain things that you cannot beat, and German precision engineering, manufacturing, and optical devices are that way.
I used to get red faced and throwing tools type of pissed off when the company I worked for would get a shipment of machines that we designed, but had manufactured in Poland would come in completely fucked up and utterly worthless. They had no quality control what so ever. Last straw was when an entire order of 36 machines came in, none of which worked. It might as well have been a couple of pallets of random parts, stuffed in boxes and labeled as such.
We beat ourselves with stupid moves like that. Germany doesn't seem to have that problem.
