Make a deal with big ag to cap food price growth in exchange for allowing ANYTHING they do to farmers. They can squeeze as hard and in as monopolistic a manner as they please on that end.

Kill two birds with one stone.

Farmers have a lot of equity that corporates could be given in exchange for lower food prices.

Prices aren't everything. Excessive pesticides can make cheap produce have negative health effects and thus a worse value. Poor soil chemistry can make cheap produce less nutritious and thus a worse value.
