Final answer:
In 1973, Nixon's agricultural secretary, Earl Butz, oversaw a change in the U.S. farm program that shifted towards promoting increased production and market forces. This change aimed to maximize output and compete in global markets.
Step-by-step explanation:
In 1973, Nixon's agricultural secretary, Earl Butz, oversaw a change in the philosophy of the U.S. farm program. Prior to this change, the farm program had focused on limiting overproduction and stabilizing farm prices through programs like the Agricultural Adjustment Act. However, under Butz's leadership, the philosophy shifted towards encouraging farmers to increase production and rely on market forces to determine prices.
Instead of paying farmers not to over-plant, the new approach promoted increased production and efficiency. Butz believed that farmers should maximize output and compete in global markets. This approach was influenced by the belief that market forces would lead to better outcomes for farmers and consumers.
