In his 1995 book “Plowing Ground in Washington”, Delworth Gardner (no relation to Bruce Gardner, afaik) asks, “Given that farm price support programs are both wasteful and inequitable, why do these policies exist and, perhaps even more of a puzzle, why do they persist?” Agricutural economists have been asking this question for decades. The answer, I think, is in the question. Farm price support programs are neither wasteful nor inequitable; an answer very few economists are willing to entertain.
