That could be it!  The tech I had was nice but not very communicative.  Maybe they are just reading what all those sound mean.  I sounded like an old ship screeching on the machine.

At least you got some feed-back.

not much - they send results to the doctor to be read.

Brain Drain is when intellectuals and upper echelon executives massively leave a country. Most of the time, this is to go towards a more profitable work market. In the current (up to now) configuration, this is usually the U.S. and Europe. But these markets may be getting saturated with over-qualified personnel, when developing countries are in increasing need of their expertise. This would explain a "reverse" Brain Drain; even if there's nothing reverse about it (it's still another case of Brain Drain.)

People answering your question think America and Europe will do nothing to stop this, but their answers are ideological. They think those developed countries would never do anything to harm free markets and free enterprise. That's not so clear.

Countries invest a lot of public wealth to ensure that we have a qualified, experienced and educated work force for those jobs that require them (academia, scientific officers, executives, etc.). On top of that, many investments are made in those countries by private enterprise (sometimes schools, sometimes companies through grants or training) to make sure that expertise is developed to the fullest. Several types of interest, both public and private, are therefore affected by these international movements of qualified personnel. A country that needs its intellectual work force cannot stand by in the name of the free market while all the brains fly away.
