It's worth noting that the 10% vs 80/95% figures are comparing different totals. For a traditional publisher, the 10% is against the price of the book (depending on the contract this might be against cover price or against the price the publisher actually receives from the wholesaler). It's not, like the self-publishing platforms, the percentage of net profit after costs like printing etc.

Yes, good point.

And once upon a time, buying, inking, moving pulp was not cheap.

Probably less than you think. When there was a lot of discussion around ebook pricing back in the day, it turned out that ebooks weren't really all much cheaper to produce than physical mass market books. The costs associated with the physical books were only around $2 per copy.
