Farm Bill blackmail!

Almost every day we are warned that we must pass a Farm Bill because, “… if we allow the current bill expire we will revert back to the 1949 law that will raise the price of milk to $7 per gallon!”  Why is it that this situation never changes?  I’ve heard this same threat for decades.   Any new Farm Bill should include a provision to repeal this archaic 1949 law and stop all government intervention in farm markets if the Farm Bill expires.
