Neville,
I agree with your point, however I was thinking about the many small to medium size operators out there that don't have huge aircraft fleets or teams of admin staff to do all the background work behind flying the aircraft and running the business. It won't take a finance degree to be a real asset to a small/medium operator.
BTW, the way pilot salaries are going it would probably be cheaper to get a pilot to do your admin, HR, rostering, tech audits etc than to get an fulltime officeworker!
