That profit pays for your infrastructure in CA. All of the trucking road taxes paves your roads, builds bridges, etc...
The best thing for this country would be if California axed their agricultural industry because it would both force and encourage Ag development elsewhere. It would simultaneously be the worst thing for Californians and the cost of food production. But why am I arguing with you? It ultimately, brings my food production closer to home and you and your neighbors bear the cost of higher food prices.
Or maybe they believe it, who knows.
