Reading the wikipedia entry on capitalism was a nice refresher. I am not an economist, so interpret as you wish: These farmers are not wage laborers. So capitalism doesn't apply. (Doubly so for sharecroppers, bonded labor, slaves. Obviously.)

My suggestion is in specific response to the observation that a financial fix would be impractical. I agree. So my proposal is to leverage Pakistan's Muslim cultural heritage. Jubilee's are part of the Abrahamic tradition, spanning Judaism, Christianity, and Islam. So maybe it'd find more traction where capitalism has not.
