Overall, I agree. However:

: A good plan, right? No, 80% of it was a waste of time, and most people make the same mistake with how they consume information every day.

>Well, yes, because a great deal would be repeated even on tangential subjects as the authors aren't necessarily assuming you've read anything else on the topic.

I also read a lot of these books and I can confirm that 70-80% of the content is unnecessary. It's mostly the author boasting about how great they or their methods are and stories about someone who implemented the method successfully. It seems that every book has to hit 200/300+ pages mark. Most of the content is just filler.
