You sure aren't. One of my buddies worked with an older woman who owned a bunch of self-help-y type business books, they were talking one day and she said, "You know, I noticed we all owned a bunch of these and it wasn't changing the way anyone worked." I thought that was pretty salient. The demand for ideas seems to be much more based on the satisfaction of novelty and being "in the know" and much less on actually utilizing any of it. These publishers try to feed that demand continuously, which is just kind of a ridiculous quirk of the human brain, and like any other irrational demand it has no inherent limit. So like you said they start scraping the bottom of the barrel.
