Most of what is farmed in Mississippi and the rest of the country isn’t food that goes on Americans’ tables. It is soybeans grown for animal feed, corn grown for ethanol, rice grown to export to Central America and so on. The fruits and vegetables that Mississippians eat are probably grown in California or in other countries.
This strikes me as a simplistic interpretation of worker and debt. The farmer who can afford to take on large amounts of debt is quantitatively and qualitatively different from the average worker. The average worker takes on debt for the prerequisites of gainful employment (education, transportation, equipment and uniform), not capital purchase for others to work on. The former gains a wage, the second makes a profit. Yes the latter is built off a proportionally large debt, but it is debt of a different nature.
