I certainly applaud any efforts to bring accessible and reasonably priced fresh food to underserved neighborhoods, but we should acknowledge that there's a fundamental conflict between the small farm locavore movement and bringing inexpensive food to poor people. Not all food at farmers markets is expensive, but it's also the case that there are reasons for the adoption of large scale commercial farming. It's cheaper. In Philly some farmers markets are mostly aimed at higher income people, while some markets, including the Italian Market, mostly obtain their produce from the wholesale produce terminal.
"Providing more inexpensive fresh produce options" and "providing fresh produce options from small local farmers" aren't the same goals.
