Where the money from your Stewart calculus book goes

Answer: Into Prof. James Stewart's $24 million Integral House.
Blogger Robert Talbert read a Wall Street Journal article on the house built by the man behind Stewart Calculus books, which are standard texts used around the world.
Talbert is a bit miffed, considering the escalation of textbook prices:
And it also makes you wonder, if you recently spent $150 on a Stewart Calculus book, what part of that house you have a legitimate claim to. If you’re a Stewart Calculus book owner, I’d say you have a right to stop in at his place for sushi unannounced at any time.
A proposition for Prof. Stewart: Now that you’ve built your dream home and established your legacy, take all of your calculus books and make them available as free PDF downloads under a Creative Commons license, so students who are spending down to their last dime on textbooks can have a shot at saving for their dream houses, too.
