“Most subsidies function as a form of so-called “farm income stabilization”. The Department of Agriculture sets a price floor for a given crop. If market prices rise above that level, farms sell on the open market. If prices fall below, the government reimburses farmers the difference between the market and the floor price for every unit grown — or not.”
