The multi-million dollar book deals politicians get raise my eyebrows.

A professor spending a year on a text might get $50,000 if he/she is lucky. Some textbook authors have made much more [Samuelson, “Economics”, etc.].

It adds that “more than $10 million of that total income was profits from Biden’s memoir ‘Promise Me, Dad’ and $3 million in profits from Jill Biden’s book.”

Very, very few actual authors, even "best selling" ones get more than $1m up front for a book.
