What we consider corruption in our country is just how you conduct business in the middle east and other parts of the world. Bribery and kickbacks are important and necessary.

I've got personal info that the reason for an Indian to go into law enforcement is for the bribe-money. They are not really paid enough and the bribery is an expected part of their income. Like how waiters depend on tips, here.

Similar with our cherished anti-trust laws. If you can collude with your competitors in a way that increases your profit, go for it!

Note: I am not excusing these practices. The part of the world that lives by a different set of rules must decide if they want their own rules to apply to their own nationals when they operate in foreign countries. It is a problem because different countries come to different conclusions.

Now we can make a big fuss about it, as you suggest, but your typical Arab probably won't understand what it is about.
