I think Joe_Bar has already had his answer Speedwoten, don't you?
If you arrive in Europe with the right of abode and are suitably qualified for the job in question you chances are equal and the law will protect you if you think you have been discriminated against. At the moment Europe doesn't need to offer any incentive to encourage anyone, European or Asian, to come and fill their job market as there is already a whole lot of qualified talent available.
Singapore Airlines, amongst others, due to rapid expansion and a lack of suitably experienced local talent, have offered jobs, (but not careers), to expats on expat contract terms and conditions to fill the experience gap, nothing else. The fact that they offer conversion to suitably experienced people simply goes to reinforce the fact that they don't, at the moment, have a sufficient continuous supple of suitably experienced local pilots.
Suggesting that Asia is more generous towards Europeans than Europe is towards Asians is totally disingenuous, if and when the pendulum swings to the opposite side the situation will be reversed. Let us all avoid making comments that have a sniff of racism about them please.
