But on the other hand though, wouldn't you say that it would be wrong to blame the teachers on the failures of the students if there is so much info, rehashed or not, available to them?

Clearly, there is enough information out there. In fact, I wouldn't be surprised if every product (or close to it) you've ever bought is already out there in a different guise.

I understand what you mean though: it sucks to buy something you've kind of already bought before, or that teaches you outdated or irrelevant stuff. It also sucks when people lie about having discovered something ground-breaking when in fact they've merely repackaged someone else's stuff.

I just find it funny that many people complain about rehashed material, but then turn around and complain that the gurus don't share enough of their knowledge. Not saying the gurus rehash stuff...but you know what I'm saying.
