Something like 80% of the people who farm for a living would agree with you.
It is the part-time and hobby farmer who is anxious for his annual stipend from the government for not growing whatever it is that he had no intention of growing in the first place.
Unfortunately, in the referenda that inform many farm policies, it is "one farmer-one vote". An Oklahoma wheat farmer working 1200 acres has no more say about grain programs than an Ohio gentleman farmer raising 12 A of oats for his horses.
Add in the agribusiness lobbyists in pursuit of pork and the farm state legislators in pursuit of perks...and you have the formula for a programmatic disaster.
