Bernie Sanders says Walmart heirs own more wealth than bottom 40 percent of Americans

From the site:

Sanders tweeted that "the Walton family of Walmart own more wealth than the bottom 40 percent of America."

The statistic correctly compares the combined net worth of the bottom 41.5 percent of American families with the six Walton family members. We think the additional points -- that many people with a negative net worth are not necessarily poor and that percentages about wealth distribution can be deceiving -- are important and interesting. Nevertheless, Sanders’ claim is solid. We rate it True.
