OK, just the cost of production then, no more profits. If it costs $200 to grow an acre of corn then corn is sold to consumers for $200/(the cost to grow an acre of corn). Education is free, so we would just train up as many doctors as needed for our population, say one doctor for every three hundred people... three million doctors. Doctors would be paid enough to buy their share of corn from the farmer. No more damn profits.
The government would be in charge of genetically modifying plants to be more productive, but no patents or profits. The new mirakul seeds (trademark not needed) would be freely given to farmers along with their diesel fuel allotments to power their state owned tractors.
Awesome!
