The key historical factor that enabled the U.S. to become a world economic and military power after WWII was government leadership in funding high-risk research and development (R&D) and the education of generations of scientists and engineers. Since 1967 the Federal government has steadily reduced funding in these areas and now is a relatively small player in our national R&D enterprise. This puts our future prosperity at risk. The book goes into great depth as to the factors that have caused this change in government policy.
You also said it’s not fair for self-publishing authors to apply those standards to editors when they don’t work with publishers themselves. It’s one thing for authors to have the right to publish their work and make it available for readers to judge its merits, and quite another for someone to ask those authors to invest in them for their expertise.
As a freelance editor, I would like to express my strong disagreement with the idea that a freelance editor must work as an employee of a publisher for three years to be any good. In my field, spirituality, many publishers have gone to having most editorial tasks beyond acquisitions performed by freelancers, so the in-house positions being held out here as a prerequisite for freelancing simply don’t exist; many editors must cut our teeth as freelancers. It also occurs to me that self-published authors usually bristle at the idea that they are not “real” authors unless their work is accepted by a commercial publishing house. Is it fair to apply this standard to the people they propose to employ as editors?

It’s always sensible to follow due diligence in submitting your first draft of your book to an editor by making as fool-proof a copy as possible for you because first, it is your own creation, and secondly, a horrid draft sent your editor can end up frustrating both you and him or her. Make your own corrections to the extent you can, so that will make the job of your editor that much lighter and the end result would be a lot more effective.
