The real issue is not race Sloppy Joe, but experience.
Some individuals (not just on PPRuNe) try to make it about race, in an attempt to brush over the real issue - experience.
When they were hiring expats, the min experience requirements to even get interview meant that only ultra-experienced candidates were considered. Post '97, with "localisation" came the idea of training locals from scratch.
As Dan Winterland correctly points out:
They're thrust striaght into the deep end - as if a new ATC cadet in the UK has been put stright into the approach controller's position at London Centre instsead of working his/her way up from Norwich tower. It's not the controller's fault. Blame the system that put them there, and the managers whose main aim is to save money.
At the end of the day, you get what you pay for. In this case, safety is being compromised to fulfil a budget.
