"The three wealthiest people in the United States — Bill Gates, Jeff Bezos, and Warren Buffett — now own more wealth than the entire bottom half of the American population combined, a total of 160 million people or 63 million households." "America’s top 25 billionaires — a group the size of a major league baseball team’s active roster — together hold $1 trillion in wealth. These 25 have as much wealth as 56 percent of the population, a total 178 million people or 70 million households." (thanks Amir)
