Its just market forces though. If no one decent wanted the job for £22k a year, they wouldn't fill the role. If they reduced the salaries of their players, what would happen?
I'm not saying its 'right' but its hardly surprising. Football clubs are large organisations like any other, they're not charities. They're not here 'for the community', its not a 'working class sport' (fans need to stop lapping up this nonsense in my view), they are no different to any other private organisation that pays its star performers stupid money and its dispensable lackeys next to nowt.
