Speaking for many I am sure..."I am not here because I want to be"..
So why not move on? Kids at school into exam years (stability), license lapsed back in Europe and hard to re-instate? Busted from Capt to FO when moving to a big company or changing to a smaller company? In the smaller company the Capt posn is where TC's are no doubt better but the pay won't help the mortgage or kids schooling bills as DXB drained people dry, food for eg is 5x the price back home, current financial commitments have to be met.
There are many reasons why people aren't moving on, there is only 1 answer I am pretty sure as to the pilots choice, they WOULD consider moving on if it was an easier option! Hence people hang around myself included but like many, our end goals are a defined target now and everyday that target is getting closer.
