Does buying used hurt developers?

I have heard from many people that the used market does not hurt developers, and this is their explanation.

When a person sells a game to the store, what do they usually use the money for? New games. And it is not like there is an infinite number of used games for the buyer to purchase. I went to a Gamestop recently because I wanted Animal Crossing. I didn't find it used, but I did find it new for a decent price, so I bought it new. Had I found a used copy, I would have probably bought it.

This is a pretty good explanation. While it doesn't give devs a sale it keeps the industry going strong.
