We've also learned about fair trade policies and I see this soon being applied here at home for buying local. The result is basically incentivizing people to perform a task at which they have no comparative advantage in. I don't mean farmer's markets are necessarily bad but I do see a pressure group growing that wishes to use government power to mandate the grown local economy. This could come in the form of school lunches being mandated to provide healthy, local diets for children. If these steps were to be implemented there would be a loss for local economies as money was poured into not the most efficient goods but the most protected goods.
