It’s important to remember people didn’t live very long compared to today. A seven year indenture is a significant chunk of one’s life. Also master-servant relations were govern by a very strict one way legal code. Indentures could be extended for violations of behavior with little to no appeal.
True. All manner of trivial “infractions” led to extended term of indenture, like for instance getting pregnant if female, fathering a child if male.
