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 person is by definition at least petite bourgeois, same as any small business tyrant with which you may be familiar. And they are publicly squawking about their entitlement to profits as a business owner. They have received over $30k/year in subsidies as a capitalist. This is the typical “farmer” PR game.
Debt doesn’t mean they aren’t capitalist.
