"As a very flattened retelling of history, it was only with the boomers that we reached the tipping point on how people started to think about copyright (Copyright != Attributed Authorship). With them, a majority started to believe in a world where the human history they consumed was a gift from the past, and that what they themselves create must be bought by future generations."

I honestly just don't know what your are trying to say and what it has to do with boomers. Are you just talking about physical media copying of books, CDs, DVDs, etc.?
