I figured it would be for different reasons.

Sklansky made his fortune through gambling (read: screwing people out of their money), and then selling books that teach other people how to do the same. Professional gamblers produce valuable nothing for society, by any stretch of the imagination. They aren't providing "entertainment," they just create a hole of -EV at the table that would otherwise result in everyone else having more money.

While I fully support the right of a professional poker player to make his living (as I am a capitalist, and no one is forcing the grown men sitting at the table to hurl money away), you can't decry professional athletes and rock stars for making millions because people want to give them money and support professional gambling.
