You do realize that is how used games work, not new games.
New games work in the same way. I've worked in a video-game store. It *might* be different where you are from. At least in Finland, shops buy the game from the importer for quite a low price and then sell it for around 70€ themselves. If they fail to sell them further, it's not the importers problem. It doesn't matter if anyone buys the game or not, bethesda has already gotten the money for it. The shop-keeper is on his own and your money does not go to bethesda directly.
Let me give you another example:
A shop has a brand new copy of Skyrim. They sell it for 1 €, if you bring three old games to the shop as well. It doesn't matter at all in which way they sell it, bethesda has already gotten their money for that copy. What you seem to think is that the shop would ship over one of the three games to bethesda, representing their share of the cake. That's not how it works.
