Although farming is one of the world's oldest professions, modern farming is affected by uniquely modern economic factors. Farmers in 2010 compete in a complex economic environment where customers choose from produce grown all over the world, and governments provide financial incentives for the production of certain crops rather than others. Although independently minded growers manage to create markets of their own through direct sales and other creative strategies, the majority of American farmers are still at the mercy of both economic factors and the weather.
The price of major commodity crops such as corn and soy depends of a variety of factors, such as investor speculation, weather and demand for these crops for both food and nonfood uses such as biofuels. Farmers who grow commodity crops earn or lose money based on the current rate that industrial buyers will pay for their output. In addition, commodity prices are affected by international economic factors, such as the weakness or strength of the dollar because, these farmers are competing not only with American farmers but with growers from all over the world.
The American government pays subsidies to farmers who grow commodity crops such as corn and soy because modern federal agricultural policy is based on the assumption that agricultural mass production benefits the economy by keeping food prices low. In theory, this policy provides farmers with a measure of economic stability, and provides consumers with affordable prices on the many processed food products made from these commodity crops. This policy encourages farmers to create an oversupply of a narrow range of crops because they make money for growing these foods regardless of current market conditions.
Labor and Immigration Laws
For better or for worse, mainstream agriculture depends on poorly paid labour that is often performed by migrant farmers, who are frequently living in the country illegally. The work pays so little that most naturally born citizens are unwilling to do it. If we are to continue buying agricultural produce at the prices to which we have grown accustomed, we must rely on workers who will work for the low wages that are customary in the field. Farming is affected by immigration laws that influence the availability of labour, as well as labour laws that allow or disallow subsistence agricultural wages.
