3% of what? GDP Dollars or Employees' wages? It's certainly not 3% of the food production since Califonria produces 1/3 of the entire nations vegetables and 3/4 of the nations fruit and nuts. And yet therein lies the problem... To many Fruit and Nuts in California.
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.
