It's a rite of passage for any kid, to set up a lemonade stand on your street corner and hawk cups of the cold, sweet drink during the long, hot summer months. It's also a symbol of our free market system, something Trader Joe's recognizes in a new commercial it's airing. The grocery store, which has been called the "Grateful Dead of supermarkets," touts our free market system in the commercial for allowing kids to run lemonade stands and explains how Trader Joe's can help them accomplish their summer dream (by offering the lemonade kids can sell of course). Unfortunately, I can't link to the commercial here because the company, known for its secrecy, has a "no blog" policy. Whatever that means. But hey, it's nice to hear the benefits of a free market talked about once in awhile.
