Ancient Egyptians were able to sell themselves and children into slavery in a form of bonded labor.

Were they? Got anything to support that? They even use the term slavery for their labor…

Edit, oh man… bad look…

Several departments in the Ancient Egyptian government were able to draft workers from the general population to work for the state with a corvée labor system. The laborers were conscripted for projects such as military expeditions, mining and quarrying, and construction projects for the state. These slaves were paid a wage, depending on their skill level and social status for their work

They even say they pay their slaves.
