Small scale farming, local is all good and merry but there's no way in the US or the world for that matter could feed the populations and no way every family could supply their own because it's not feasible. Take for example one block in a big city can have thousands of people. 8,000-10,000 in just one giant sky scrapper during a workday in NY city alone. It maybe sad the conditions and practices of some factories but large scale factories are a evil necessity to supply the needs of our populations.
