A top Kroger executive admitted under questioning from a Federal Trade Commission attorney on Tuesday that the grocery chain raised its egg and milk prices above the rate of inflation, a concession that came as no surprise to economists who have been highlighting corporate price gouging across the U.S. economy in recent years.

The U.S. grocery sector—dominated by Kroger, Walmart, and a handful of other major companies—profited hugely during the Covid-19 pandemic as corporate giants exploited supply chain disruptions to aggressively jack up prices.

“The grocery industry, as represented by four of its largest players, became more profitable in the pandemic, and it has stayed that way for a couple of years at least,” The Financial Timesnoted Monday. “It is a good guess that price increases in excess of cost increases have played a role in this.”
