I guess at least in the light of above exodus people will understand the complex role played by expats in sustaining lower pay packages for local pilots.
Most locals will be willing to jump in with "expats are too expensive arguments", but will ignore how subtly a small number of expensive expats keep a sufficient downward pressure on local salaries and prove an overall cost savings for airliners which employ them, and are way too reluctant to do away with them.
Of course all this is without any willful complicity of expats, they are not to blame for it.
