As stated by hangar 6, the IAA is completely separate from the Government and is totally self funded. And to be honest the IAA is one of the more professional Aviation Authorities in Europe. Plenty of information on their website if you require it!!!!
I think you should look more at the ridiculously poor pay you American regional guys are on for your flaws in safety. A huge amount of your regional guys must undertake a second job hence are exhausted whilst in the cockpit. I believe tiredness in this instance has more to do with lack of safety rather than less hours.
