What we've had in the last decade is a rare combination of mainly loco growth, but also looser medicals, more immigration and the final realisation that to fly an A320 you don't need to be the top 0.1% of the population.
So demand has gone up, but supply has massively.
The T&Cs are still not clear to everyone however because legacy pilots are still earning good money.
There will be growth in Asia, but let's forget the big expat packages.
I don't see it changing as I do think that it's a less demanding job for most of the time than it was yesteryear.
