"Many pilots Leaving?" BWAHAHAHAH!
More like, who the hell is actually applying/joining these days? It was a "need to feed my family cause I'm unemployed" acceptable option for a long time but now it seems to have descended into the "not even if the only other option is Ryanair or driving a lorry" category. (I'm referring to new-joiners, before the old-timers get grumpy and defensive.)
You can't really use the "at least it's a job" excuse when it's not - you move your whole life to the ME and you're chained to it for minimum five years.
My sympathies to those who truly believe they have no other option.
