If you see who's behind it, you will see where the technical skills will come from. For the majority of the work, it will be an unskilled Chinese worker who has had a small course and will probably only be trusted with one or two jobs which he will become very proficient at. They will probably have a reasonably large workforce because when you are paying a bowl of rice a day it doesn't add up to all that much. It is worrying that it is cheaper to fly an aircraft to the other side of the world for its maintenance that it is to have it done locally.
In theory, what they are doing make financial sense but I do worry that the unusual thing that comes along will be missed because they don't have the overall experience to know its wrong. You won't get any of that annoying H&S nonsence out there either.
However, I have heard stories in this country of people like BAES hiring ex butchers and bakers and turning them into riggers after a small training course so its nothing new.
