...In that they don't understand quite where it comes from. 
 
In response to Retailers are "Parasites" and "Theives" a story by Jim Sterling
 
Publishers do not sell their games to people, they sell their games to intermediary companies that deal with people, companies like GameStop or GAME or TESCO even. They make their money right off the bat before anyone else can even see the game box-art on a shelf.

I agree with everyone in the comment thread coming off of the story, in that if they want MY money, sell ME the game. When I'm done with it, I may sell them it back to get my next one although it's my own preference and good fortune to be able to choose not to do that most of the time. I'm quite relieved that when I looked down into what other people were thinking it reflected my own stance, proving that It isn't a problem with my thinking.

The Used game market is also my right to choose not to give a publisher my support though these legitimate channels if I choose to. It took a full three months, but I waited patiently for a copy of "Tales of Vesperia" to be sold into GAME because I was disgusted that it took a full year for it to be translated from American to English. I could still enjoy the game that I waited 2 years for after it was completed,  but it empowers me to make a choice with my wallet.

Personally I love buying games brand new day of release if I believe the game will be fun (hell, the hype around here for "X-Blades" had me buying that day-of) but Publishers have to realise that that money isn't theirs when I go to GAME and get my fresh-plastic smelling cellophane wrapped DVD box full of software and copyright leaflets. 
 
There are other arguments in favor of the used game market, but my real beef is with how pissy publishers get about it, considering that if I buy a game at a store, they don't get any of that money anyway.
