Newsflash; People buy hype
The average person doesn't get excited about conservative financial matters. They want to hear about big returns. Even after Madoff et al. I'm willing to step out on a limb hear and guess that most buyers of gambling books are men. Furthermore, they are between the ages of 25 and 48. This same age group is a pain in the neck when discussing investment or insurance issues.
They are do-it-yourselfers and think they are getting screwed by anyone selling anything. They don't want anyone making money "off of them". God forbid your advisor or t.v. salesman actually makes enough money for gas and food. They don't understand that the more the salesperson makes, the more service they will get (or at least can demand). Just learn to choose people you can trust. They think they can make big time returns and get Warren Buffet rich.
My best customers are single women in their late 40's to mid 70's. The younger group have gone through divorce and have raised children on small incomes. Once I earn their trust, they ask me what they should do. They are con=servative and not pre-occupied with getting rich. They want security first. Men seem to never fully trust and are always looking for something better. Near retirement or retired men are a bit better.
I think it's the nature of the demographic that sells Patrick's books. If SW re-writes Professional Blackjack and intersperses stories from his days as a pro, he would sell more copies. He likely has a ton of stories from all over the globe that would captivate a reader. The reader may skip everything else, but SW would not be to blame as long as the info is there and he'd make more money. Uston's Million Dollar Blackjack comes to mind.
SW would have to change the title to something like "Get Freak'n Rich Beyond Your Dreams off those Greedy Casinos!" Of course, buried in the text somewhere, he could clarify that a huge bank, lots of time and travel etc... would be needed. This would alleviate his better moral character from the guilt of misleading readers. Patrick apparently has no such moral standards.
