You can't. If your people do not feel the need to live humbly and serve their country they are going to flock elsewhere to the highest bidder. If a German engineer finds $30k/y after tax to be an unacceptable salary what are you going to do about it? Brainwash him into sacrificing for their glorious Fatherland and just shutting up and doing the work?
Uh, you forget that those US companies make a profit off of those engineers! How you break the cycle is simple: you find a way to pay those engineers more, so they stay at home AND you put the profit in your pocket. There are plenty of large companies in the EU that could do this.
But they don't. They're too cheap, or perhaps EU style managers can't stand the idea that some people in the same company as them make half as much as they do.
