70% of US engineers are of german origin what are you talking about?
One of my former colleagues (electronic engineer) recently moved to Germany (from Russia). A week or so ago he was back in Moscow for a few days to visit their parents. We got some beer and talked a bit...
Their first opinion after half year in a large German hi-tech company - there is about 5% is older German engineers, really smart and experienced ones, real "stars"... About 20% of remaining native German engineers is average-to-good, notning special. The rest cannot produce something new, good once you need to make DIN-standard paperwork or something similar, but no creativity at all.
As he said, it looks that 60% of new ideas and solutions come from 20% of immigrants working in their department. Serbs, Russians, Poles..
As to this topic - I was really shocked once I drive all the way from Lithuania to southern France and back late last year (first time in my life made such trip on a car). Belgium looks like patient with terminal stage of cancer for a "fresh eye".... In the middle of workday, I seen LOTS of blacks and arabian-looking guys, without any hurry walking down the streets and sitting in street cafe... More than european looking people..
And, maybe someone can tell me which business may nave a horde of 40-50 arabs (including 12-15 yrs ord girls and boys) on a gas station, near toilets, in the middle of the night? (It again was in Belgium, on my way back).
