Wages have also risen sharply since the pandemic, and have outpaced prices for more than a year. Still, surveys find Americans continue to struggle with higher costs.

“We all know that prices went up during the pandemic when the supply chains shut down and failed,” Harris said Friday in Raleigh, North Carolina. “But our supply chains have now improved and prices are still too high.”
