I'm in Germany, and you may have heard on the news that we have a lot of refugees/immigrants from places like Syria who we are trying to integrate into our society. A lot of them are very qualified. Some of them have since gotten advanced grad degrees from German universities.
And then we may not be able to hire them or have to severely restrict them at work, e.g. when we use Qualcomm chips which are under US export restrictions.
I don't have a very deep point to make, except to say that the human costs and the stings that come with the state of the world can go far indeed.
These people did not just willy nilly decide to move to Germany. They had to leave their home country because of a civil war. At least they're safe, but they're being held back by illogical bureaucratic hurdles.
That statement is quite in conflict with reality.

Hardly any notable amount. It's not the great tragedy you seem to think it is.
