In a 2006 “Saturday Night Live” sketch, Chris Parnell sums up the conventional wisdom about credit card debt:

“Did you know millions of Americans live with debt they can not control? That’s why I’ve developed this unique new program for managing your debt. It’s called, Don’t Buy Stuff You Can’t Afford.”

According to the prevailing story, debt is caused by lavish and irresponsible spending by poor and middle-class families. But like much “conventional wisdom,” an increasing amount of evidence belies this point. In fact, the decline of saving and the rise of debt was an almost inevitable consequence of families trying to scrape by in the face of rising inequality. This is the corollary of French economist Thomas Piketty’s now-famous observation: While capital is increasingly concentrated at the top, it turns out that debt is becoming concentrated at the bottom.

In the same “SNL” bit, Amy Poehler says, “There’s a whole section in here about buying expensive things using money you save.” This supposedly common-sense observation is mirrored elsewhere. The American Institute of CPAs runs an advertising campaign urging people to “Feed the Pig.” One such ad depicts a responsible couple studiously saving for a house, while another eats lobster, receives massages and then complains about “never having enough to put away.” Underlying both the real commercial and the satirical one is the idea that those who aren’t saving could do so, but are instead spending the money. But the evidence for this story is weak.

A more compelling story is that inequality has made it harder for households at the middle and bottom to save. In fact, the decline in savings has coincide with a rise in income inequality (see chart). There is evidence that these trends are connected.
