Not that long ago a friend of mine, american banker, told me, that the one of several reasons of Subprime Mortgage Crisis in USA was consequences of that stupid political correctness - bankers weren't "empowered" to say NO to afroamericans (omg, "afroamerican" indian tea, "afroamerican" square by Malevich, "afroamerican" pawn in chess...) because in case of saying NO they (bankers) could be sued for racial discrimination.

Then bankers had the first tide of "dead" subprime mortages because of afroamericans and therefore the whole system collapsed.
He didnt say that was the only reason, but he said that was last stone.

What do you think? :>
