Tap, I think you are on to something. I believe we need to define exactly what the Dept of agriculture is really supposed to do. Today it is trying to wear to many hats.
I believe it is there to help both the producers and the consumers. It should not try to set prices or work with world trade. That is a job for those in marketing.
Farmers and ranchers should have a means to establish their prices so as to cover expenses and a reasonable profit, not a price suggested by government. Consumers will have to pay whatever the price that is asked. Some will be able to produce cheaper, this is where competition comes in. Why should food be priced any different than, lets say, the automoble that you buy.
