Jim Cramer *is* rich beyond belief. OTOH, I'm not particularly convinced that the ordinary guy can get rich with Cramer's picks.
People who criticize Cramer's stock picks miss the point, I think. He gives insights in how traders think and demonstrates that you don't need a crystal ball to make money in the market.
In my experience, buying stocks is relatively easy and the TV experts sometimes do give useful tips. Knowing when to sell is a lot harder, and you almost never hear anyone talk about this.
