Sometime I wander why they pay big bucks to all those big rating agencies / auditor companies/ financial market consultants and so for;

It would have been much cheaper to delegate those ratings / auditing / analysis gigs to a bunch of chimps in a state zoo!

You go to the chief-chimpanzee on duty that day with your financial product in one hand and a nice bag of bananas in another.
If he smiles at you and makes those cute chimp noises (while grabbing bag of bananas) it means your financial product
(Hi-grade-sewerage-froth-star-fund) is stable and you got AAA rating!
If you are big corporation, you go to chief-auditor-chimp with your gold-wrapped balance sheet, show your papers, offer bag of bananas and you are good to go into the next year. All happy with solid 4th quarter growth & positive outlook for the first quarter of the next year!

And so for. If you are country...

Why give huge bucks to all those hi-class Harward educated nerds inside large glass&marble buildings, when it all end up being
bananas at the end anyway? :)
