The average American household carries $137,063 in debt, according to the Federal Reserve's latest numbers. Yet the U.S. Census Bureau reports that the median household income was just $59,039 last year, suggesting that many Americans are living beyond their means.

Those numbers are unlikely to shrink anytime soon, according to NerdWallet. That's because the cost of living in the U.S. rose 30% over the past 13 years, yet household incomes only grew 28%.

Medical expenses have grown 57% since 2003, while food and housing costs climbed 36% and 32%, respectively. Those surging basic expenses could widen the inequality gap in America, as a quarter of Americans make less than $10 per hour.
