Your above contention is probably (/possibly) correct, though I would hesitate to put it just like that. The real issue is to prevent/minimize the number of such "doorstop" (i.e. useless) books  the enormous number of trees that are cut to produce these books are a real issue.
(I must confess I have not examined these school texts at all, so I wouldn't really know what is useful and what is not  I assume there must be plenty that's valid in Domenico Rosa's oft iterated remark).
I DO know, however, that: we're wasting huge resources in every way, every day. We do need to get a hold on that.
(See also the recent thread on the "exponential function". With that kind of thought in mind, I AM led to wonder what might have been the underlying reasons for Haim's and Robert Hansen's many posts deriding a process that could help us understand the significance of the 'exponential function).
