Advances, editing, art etc are all sunk costs. They're paid only once, amortized over the whole run and eventually can be paid off entirely.

Manufacturing is a marginal cost that is paid per book and never ends. (The same applies to royalties).

What this means is that as the number of book sold increases, the sunk costs count for less and less while the marginal costs become totally dominant and eventually the only real cost after the sunk costs are completely covered.
Marginal costs only become dominant when the print run is very large. Very few books have a print run over 50000 or so.

My statements are correct.
