Will millennials kill Costco and Sam's Club?

The Chicago Tribune reports:

Warehouse clubs and supercenters cut an average of 2,500 jobs each month in 2017, reversing a longtime trend of steady growth, according to a Washington Post analysis of Labor Department data. Between 2009 and 2016, warehouse stores had added an average of 3,000 workers each month.

The sector received more bad news this month, when Walmart announced it would close 63 Sam's Club stores, affecting an estimated 10,000 workers. In a tweet, the company said the closures would help "better align" its physical locations with its strategy. (Ten locations will reopen as e-commerce fulfillment centers.)

"Today's adults are not spending a lot of time shopping like my parents' generation did," said Kim Whitler, a marketing professor at the University of Virginia's Darden Business School. "Gen X, Gen Y, Gen Z, they're all time-starved and want to order groceries while they're riding a bus to work."

The changing world of retail.
