Query: DVD Region Codes

I would like to take this opportunity to complain about the region codes of DVDs. I think that they are a major nuisance and just the consequence of the sort of greed that brought the global financial system so close to collapse. They serve no other purpose than squeezing a maximum of dollars out of the pockets of customers. Amazon as a major buyer might very well be in a position to do something effective against this nonsense. Would be great!
