Writer Helaine Olen has a young son, and he engaged in a classic American summer activity: he started a lemonade stand on his quiet suburban street. He earns some spending money and probably learns some important lessons about customer service and profit, and the neighbors who patronize his stand get a refreshing beverage. But, Olen writes, her son’s customers want more than that. They ask what charitable cause his lemonade stand is raising money for, and disapprove when they learn that his stand is a for-profit venture. What the heck?
