Dollar General's CEO says financial stress is climbing the income ladder, with upper-middle-class Americans now shopping like low-income households — bad news for retailers, restaurants, travel, and the broader economy.

• CEO Todd Vasos told a Goldman Sachs retail conference that even customers earning $100,000 or more are now under real financial pressure.
• The main cause is gas above $4 a gallon and diesel near $6, on top of years of high prices for everyday goods.
• Whenever gas crosses $4, Dollar General's shoppers stay closer to home, shop more often, and buy less each trip — and that is happening now.
• With over 21,000 stores, Dollar General's data is one of the clearest real-time reads on how ordinary Americans are spending.
• The shift hits far beyond discount stores: travel, grocery, and restaurants all feel it when the middle class tightens up.

Outlook: The Trump administration is scrambling for energy price relief before the midterms, including possible diesel export limits and more refining capacity, but none of it will bring prices down quickly.
