To add to Minda's post - we're not going anywhere (at least en-masse), for the reasons he stated. In fact, there is a process opposite to what most of the "westerners" fear. Out of four airlines operating from my country (Poland), two hire mostly foreigners. Not because we lack English, experience, whatsoever - there are a lot of guys that meet or exceed "western" (as some call it) standards. It's because the western Europeans are cheaper! Sounds crazy, doesn't it? However, many experienced "home" pilots lose competition with 200-hr wonderkids from Sweden or Great Britain, simply because they cannot afford to buy a type rating and work for peanuts just to gain experience. Those guys come here, get a few hundred hours being paid cr@p and leave to the west, just to be replaced by newcomers of the same kind... I am not complaining - after all this is what EU is about - anyone may work wherever he wants... I just want to point out that expansion of the EU has created more workplaces for pilots from both sides of the curtain...
Cheers!
P.S. I see some idiots here think they are a better kind, just because they hadn't have Ivan telling them what to do for last 50 years...
