"In addition, farmers destroyed crops and livestock to comply with the policies of the New Deal administration, especially the Agricultural Adjustment Act of 1933, which was designed to raise and stabilize farm prices, conserve soil, and control production. It can be argued -- and has been argued -- that FDR's economic policies backfired, solving no problems and prolonging the Great Depression."

"The Agricultural Adjustment Act of 1933 similarly restricted production to keep prices high. “Excess” output was destroyed or dumped abroad. While millions of Americans were going hungry, the government plowed under 10 million acres of crops, slaughtered 6 million pigs, and left fruit to rot."
