In 1929 rural sociologist Rupert Vance surveyed the southern landscape, seeing no end in sight to the cotton production that impoverished the South. In search of ways for cotton farmers to diversify, Vance noted that "whether equitable or not, a system of division of the product by shares between landlord and tenant has been worked out by custom and law for cotton." Indeed, there was a credit system in place that facilitated cotton production, a system that dated back to Reconstruction. Lamenting that "no generally accepted system of share cropping has been worked out for more complex forms of farming," Vance could not foresee that soon furnishing merchants would refashion the crop lien to facilitate poultry production. For some time, politicians, Vance, and a host of rural reformers waged an unsuccessful war against the crop lien, and its close relatives sharecropping and tenancy, which they considered to be the basis of southern problems. The poultry industry - today the model for contract farming and a multi-million-dollar business - grew out of the crop lien system, an institution thought to be the root of southern poverty
