"ONCE AGAIN we stray into the pointless territory of 'who is the better pilot'/'which is the best training regime'.
That is not the point."
That's right, it isn't the point at all. Uncle Sam isn't "stealing" European flight students, they come of their own free will for all the reasons stated many times before.
If you want to see a United Europe for aviation matters and make it cheaper at the same time too, then you have to change it to make it work how you want it.
Protectionist moves to limit choice rarely work well. As RRAAMJET said, if you want to work in a country not of your own nationality, then you need to address the issue of the work visa problem first...and it's not impossible to do so.
There is always a way round an apparently impossible problem.
