According to a 2014 report by the National Bureau of Economic Research, the wealthiest 1% of U.S. households own about 42% of the country's wealth. On the other side, the share of wealth owned by the bottom 40% of U.S. households amounts to just 0.3%. When it comes to income – the stats are the same. The top 1% of U.S. households earn as much annual income as the lowest-earning 40%.
America's four wealthiest families own as much as the bottom 40% - that’s 128 million people whose combined net worth is matched by the wealth of Bill Gates, Warren Buffett, and the Koch Brothers.
