The rich are getting richer and The Forbes 400 list of the Richest Americans is out to validate it. The big list of people with big-money is out and and the eligibility to enter it comes for a price of $1.7 billion. And because the bar is so high, 145 U.S. billionaires failed to make it to the list. Though down by $5 billion, Microsoft’s Bill Gates still walks away as the richest American for the 22nd year in a row, with a net worth of $76 billion.
