Good points. Thank you all.
I singled out books because I'm invested in the industry personally.
As a writer I'd be lying if I said I didn't get a twinge whenever I buy a used book knowing that no part of my purchase is going to support the author. That's pretty much the whole of the issue.
Of course with Borders closing, a used book store is the only book store left in my town so I guess the problem has been solved for me
