No offense, but I suggest you know little about farming. You must understand farming inputs and the big variable over which you have no control is THE WEATHER. There are years where Midwest average corn production might be 140 Bushels/acre and others, like this year, when it is less than 50 Bu/acre in some areas. We do not have excess year after year, there is a certain amount of carryover corn that acts as a buffer to prevent shortages, but in many years the carryover gets used up.
It has always been government policy to keep food cheap, hence the prime reason for subsidies in a vary volatile industry. Abscent controls and subsidies, think about food prices doubling and shortages occurring. Not a pleasant prospect.
Farming is extremely unpredictable and highly stressful to producers. I sometimes wonder why I do it, even on a parttime basis. It makes little money and I hate the stress of depending on weather. I could go on, but you get the idea.
You're probably right about my knowledge of farming. OTOH, is it not also true that farm subsidies have the effect of driving down prices and making it more difficult to make a profit on what you do produce?
