Cramer is a front man for the markets and an entertainer. He gives the impression of passing along market wisdom when it's just another attempt at covering up the rigged game.
In that way he belongs with the other two looters.
I wouldn't take any of those books for free unless they threw in winning megamillions tickets.
On the other hand, they could be used as kindling when the economic collapse comes.

While I disagree with Jim Cramer's politics, his investment advice has been sound over the years. He does not deserve to be lumped with Hillary Clinton and Tim Geithner. I have actually bought and read two of Jim Cramer's books. They were clear, concise, and easy to learn from.
