Grain embargo essentially destroyed the US Agricultural market, permanently. Domestic prices for Wheat, corn and grains plummeted, international prices soured. Places like Chile bought as much as they could and sold to Russia at inflated prices. Then hired US Agricultural professors to come to Chile, Argentina and Brazil to teach them modern farming technologies. These professors were WELL PAID, so naturally they did this.

Now, the world leaders in Wheat production are Argentina, Brazil, Russia, India, U.S. and China. We used to dominate. and essentially fed the world. Carter gave us the highest inflation we ever had, gave away the Panama Canal, the worst unemployment and who still remembers the lines for gas or the US Hostages?
