Because They Work So Hard.

"In 2007 the total wealth of the Forbes 400 equaled the wealth of the bottom 50% of families in the U.S; wealth held by the Walton-six (the six heirs to the Walton fortune) was equal to that of the bottom 30.5%."

Let's see, 400 people vs. half the US population, or 156,974, 500 people....


So that's only because the Forbes 400 worked 392,436 times as hard as each American in lower income half of the population.
