Bribery is the norm elsewhere, while the US has (openly) banned it. Therefore, there has developed a double standard, and a catch 22 for US businesses trying to operate in the rest of the world. Just another example of the US trying to take the high road instead of dealing with reality.
I will say I love the fact we (basically) don't have bribery IN the US, other than the legalized versions (unions, permits, etc).
