In 1970, about 40 percent of the nation's wealth was held by 10 percent of the population. Today, almost 40 percent is held by just 1 percent of the population (and over 70 percent is held by just 10 percent of Americans). But we still have people arguing to reduce taxes for the wealthy. How big does the wealth gap have to grow until people realize that the trickle-down effect is a failed economic theory?
