America still has a farm problem, though wartime prosperity has hidden it for the time being. The problem, simple stated, is this: Farm produce supplies are out-running demand. The main forces responsible are: (1) a slackening in the increase of population, (2) the fact that people spend smaller proportions of their incomes for farm products as they grow richer and (3) the revolution in agricultural production methods.
