Adding to this, indentured servants still had some rights (though these were often disregarded as the people who violated those rights were often the ones who would enforce them). Examples:

• Indentured servants were allowed to read. Slaves were not. Teaching black slaves how to read itself was a crime punishable by imprisonment and/or lashings.
• Indentured servants were still allowed to own property. They often sold as much as they could, however, to pay off their debt. Slaves owned nothing. Even their clothes were property of the master. Slaves were not allowed to buy or sell things for themselves.
• If you killed or seriously harmed an indentured servant, you could be charged with a crime. Some contracts had limits as to what types of punishments could be dealt to the indentured. Slaves could be murdered,removedd, and tortured with impunity.

Having an impossible sum of money held over you with your wages garnished under the threat of imprisonment or abuse was awful. But it still isn't as bad as some Epstein frat boys deciding they're going to use you for skeet shooting. Or sending your children to another plantation in another state where you will never see them again.
