Health can destroy wealth.

Just in the past year, Americans borrowed an estimated $88 billion to cover health care costs, according to a survey from West Health and Gallup[1], released Tuesday. What’s more, 45% of Americans are concerned that a big health event could cause bankruptcy.

They’re right to be concerned. More than two in three bankruptcies are caused by medical problems, either from bills, income loss due to illness, or both, according to data released this year in the American Journal of Public Health from more than 900 Americans who filed for personal bankruptcy between 2013 and 2016[2]. Other surveys[3] come to a similar conclusion, noting that medical issues are the No. 1 cause of bankruptcies.

Even insured and financially comfortable people aren’t immune. In fact, it’s mostly people who are middle class and have insurance who are filing for bankruptcy, David Himmelstein, the lead author of the study, tells MarketWatch.

“Unless you’re Bill Gates, you’re just one serious illness away from bankruptcy,” says Himmelstein, a distinguished professor at the City University of New York’s Hunter College and lecturer at Harvard Medical School, in a statement. “For middle-class Americans, health insurance offers little protection. Most of us have policies with so many loopholes, copayments and deductibles that illness can put you in the poorhouse. And even the best job-based health insurance often vanishes when prolonged illness causes job loss — just when families need it most.”

Consider this staggering fact: In 2018, the average cost of health care for the typical American family of four covered by an average employer-sponsored PPO plan was $28,166, according to the Milliman Medical Index. Every month, this rises roughly $100, the index found. And imagine how high these costs might go if you had a bad accident or prolonged illness that meant you couldn’t work, resulting in loss of your job and the insurance that came with it. “That’s the triple whammy,” says Himmelstein.

Medical issues are all too common, too. Indeed, 44% of Americans got hit with a medical expense they didn’t expect in the year prior[4]. And for too many, it’s devastating: 530,000 families go bankrupt each year because of medical issues, the American Journal of Public Health revealed.

And yet, far too few of us have money saved to handle these issues. Four in 10 Americans don’t have the savings to cover an unexpected $400 expense, according to Federal Reserve data released in 2018 — and more than one in four skipped necessary medical care in 2017 alone simply because they can’t afford the cost. What’s more, research shows that FSAs are underutilized. [5][6]

Why do we have so little savings for medical costs? “It comes down to human nature — a combination of being focused on other things that seem more urgent, and flat out being in...
