In some parts of the world (Singapore, Malaysia are places I have seen) there are shops in malls that openly sell copies of stuff. In fact when I first bought a PS3 and went looking for games for it in Singapore I was frequently turned away with "Oh, you want originals? We don't do that here".
...coupled with the "legitimizing" effect of paying some amount of money for something. aka "You wouldn't steal a car would you?" "No, but I might pay a dollar for it".
