Farmer's Return

I heard an interesting report~ The farmer gets about 20% for every dollar spent at the grocery store on his/her produce. Who gets the rest? Some is spent on regulations, trucking, store overhead, marketing, and... The list goes on. The really interesting thing is this is down from the 1994 levels where a farmer recieved about 25% of every dollar. High input costs have dramatically decreased the profitability margin of farming. Then you add on to it the increase in regulations, fertilizer costs, land costs and niche marketing issues. Doesn't seem like a very profitable way to go... So where is this big business agriculture that is just in it for the money? I dunno!
