This week, I thought I would write about food stamps and farmers markets. People on food stamps, officially known as the Supplemental Nutrition Assistance Program (SNAP), receive their benefits on a card that can be read like a credit card. Crucial to allowing recipients to use food stamps at farmers markets are card readers. The U.S. Department of Agriculture just canceled its contract with the company that makes the card readers. As a result, food stamp recipients will likely lose the ability to use food stamps at farmers markets. I was all set to write about this terrible mix-up. But then I realized it’s not the part I really care about. Of course, food stamp recipients should be able to shop at farmers markets. But it’s a tiny part of a much bigger issue. The diets of food stamp recipients lie at the intersection of two issues: our food system and economic inequality.
