However, it is probably comforting to those who aren't rich, particularly if they are looking for a justification for looting money from the wealthy.

Some background on the Forbes 400

...Indeed, of the charter members of the first Forbes 400, only 32 remain today. Far from a country where only the rich get richer, the wealthy in the US are very much a moving target. While there are 74 Forbes 400 members who inherited their entire fortune, 270 members are entirely self-made. Though many attended Harvard, Yale and Princeton, there are countless stories within of high school and college dropouts, not to mention others who grew up extremely poor. Politicians who regularly engage in class warfare would do well to keep the Forbes 400 out of the hands of their constituents, because it makes a mockery of the kind "Two Americas" rhetoric suggesting the existence of a glass ceiling that keeps hard workers at the bottom of the economic ladder. To read the Forbes 400 is to know with surety that the U.S. is still very much the land of opportunity.
