An economist offered an explanation for a paradox that has emerged in recent data showing that spending has remained robust even as consumers report feeling pessimistic.

Joanne Hsu, who is the director of the University of Michigan’s consumer sentiment survey, told CNBC on Friday that she thinks Americans have abandoned plans to save money as they see their financial goals look less attainable and are spending money instead.

“This positive spending is not a reflection of some sort of internalized secret sense of confidence that consumers have,” he explained. “And instead my interpretation is that consumers see that a lot of aspirational goals that we talk about as part of the American Dream—homeownership, paying for college, paying for college for your kids, having a comfortable retirement—with high prices and high interest rates right now, those aspirational goals just feel increasingly out of reach.”
