That might sometimes be true, but the textbook the OP referred to is less than $16.00:

Which is why no one will ever use it, because you can't justify a $200 price tag for a 100 page text books.

e.g. no college will ever endorse this book as a text, because they need to sell 60k in calc 101 text books each semester so they can get their cut.

Yes, fair enough, however I think the discussion is not so much about schooling as education. Not all education takes place in college -- and with costs rising as they are, I predict a future with many more autodidacts -- self-educators.
