Do we really need farm workers? Then why is nobody paying them? I think most stories about poor farmers is about farmers who want to farm in a more traditional way, while actually most stuff is produced in huge enterprises that don't need as many people to run anymore? Nothing against farmers, just would like to see the real picture. In any case, if farmers are needed and still don't get paid, there has to be a reason, and it presumably isn't the markets.
