Anecdote: One day a friend asked me to look at their family member's doctorate because she was having trouble with the analysis section.

All I could do to save face was point her to some resources, because if I said what I really thought, it would be in a trash can set on fire.

Or to put it another way: maybe they don't do it, because if they did, it would stop the requisite amount of papers being published.
