Again, the same arguement crops up. Airlines/Airports are run by Accountants who have no idea about operational matters, nor do they have the foresight to budget for future staffing. I forsee within the next couple of years that some airports will have to either spend loads of money training staff as there will not be any controllers around or they will have to limit the services provided to the airlines. The latter is the favourite due to the inept management policies. Another way around the staff shortage would be for the government to step in and say "hang on, what's going on with our aviation industry. Why do we have such a shortage of qualified staff". Unfortunately this will not happen and the industry will still be run by financial idiots and any shortage will be dealt with on reaction rather than prediction.
