Why do we subsidize farmer's during hard times, but not get cheaper produce when profits are rolling in?

Farming as it was once known i.e. the family owned and operated farm, has all but disappeared. We now have Corporate farming, and as you should know the Government is all for giving corporations a hand out. Same as the oil Company's, they are making record profits, yet gas is going up,and up. If any one out there really cares about the plight of the few small farmers that are left, you will buy locally grown produce and if there are no farms in your area, buy organically grown produce from your market, traditionally this produce is grown on a smaller, independently owned farm. We do not need Proctor and Gamble growing genetically modified food for America.
