Cotton/plantation sharecropping, ~1860-1950 in the US south. https://en.m.wikipedia.org/wiki/Sharecropping https://en.m.wikipedia.org/wiki/Sharecropping Generally exploitive features include: an exclusive buying right by a certain party (allowing them to set prices), incidentals and necessities of life only being purchased from a certain party, mortgaging future assets in exchange for current goods/services (often with steep or complex credit terms), and restrictions on free sale of assets to arbitrary third parties (preventing price discovery and realization of fair market value). As GP observed, these specific modern agreements generally avoid those pitfalls.
