Staff-size or process issues could be part of the problem.
I know, for instance, that many novels have at least 3 editors work them over before publication...and that's not including the guys & gals who do the brute force typo/punctuation stuff. I'm talking about people whose job it is to read the material in its entirety and with attention to the minutiae and see if the plot flows, if continuity has been affected by edits, if the quality of the writing is up to snuff, and so forth. These people are going through the text with a writing implement making notes, etc., just to make sure they're putting out a quality product.
Most writers hate them; all writers need them.
And even with that, the occasional typo slips through. I caught one in Susannah Clarke's Jonathan Strange and Mr. Norell, about 70% of the way in. It was minor, but jarring enough at the time that I had to back up and re-read certain portions of the book just to make sure I wasn't going nuts. I didn't see any other errors, though.
(And at this moment, I don't recall exactly what it was. I think it was something like the use of a homonym- something most live editors would catch.)
