There would be an appendix of good ideas that have been taken up without the inventor having to struggle, too, to show that this can happen as well.
The book would show the danger in going overboard in taking up a great expensive scheme without pilot studies, just because conmen and charismatic people can be plausible, and greed can be blind (eg South Sea Bubbles and groundnuts in Africa) and how easy it is to say 'no' to quite simple schemes, as a reflex. It would quote Northcote Parkinson. And it would show how easy and valuable pilot experiments often can be - instead of crying 'no, it can't be done' as a matter of course.
There could be one edition for 8 to 12 year olds, in every school, another for 15 years upwards, and a third edition, possibly in chronological volumes, for institutes of tertiary education - with all editions of course available for general sale.
