If, through what ever means, the supply of milk in the U.S. could be brought completely in line with demand, there would still be the problem of determining price. Who will decide what farm milk is worth?
Those, between the farm and consumer have taken an ever larger slice. If the farm is going to get more for a balanced supply/demand, the money will have to come from somewhere.
Sooner or later, the logistics of the supply chain will need to be examined. So far, no one has expressed an interest.
