There has been and NEVER will be a shortage of low time inexperienced pilots.
There IS a shortage of EXPERIENCED high houred captains and TRE/Is on certain specific types that are willing to travel to the ar*e end of the world as expats.
By the time that the low houred inexperienced pilots have attained command and experience these contracts will be long gone and the developing/3rd world countries will have sufficient local man/woman power in order to recruit internally.
