pride is the source of shame
He should not have brought this topic up.
"Seemingly reasonable actions or conditions the indentured person has to fulfill, which of course they can't in practice. Or actions the contract holder can do that lets them add on time. Sometime in the contract language itself, sometimes in the law."
He'll choose examples not related to his own tricks with loans.
"For instance, the contract providing for the master to pay for healing for the indentured, but it adds on a lot of time, implicitly assuming the healing is implausibly expensive and the indenture's laborer's worth for each day implausibly low. And it doesn't have an exception for the master themselves inducing the injury that needs healing. So periodically the master beats the servant near to death, then pays for their healing, and can keep it up nearly indefinitely. For another example... by law, time spent pregnant or recently post pregnant doesn't count towards the indenture. But the master can compel work during this time anyway. And inducing time pregnant is in fact trivially easy for the master, and the indentured servant has no way to protect themselves."
"Those are just two examples. For a more recent example... there are probably tricks with swapping value between paper and metal money that could be applied to indentures. I know for loans at least... my wizard school recently had a too-generous offer of refinancing I shouldn't have trusted. There are enough tricks out there I wouldn't confidently bet on anyone's ability to list them out and ban them individually, as opposed to simply making blanket bans on any attempt to extend indentures. If we try to stop it at the convention... probably some Abadarans will complain, but I don't trust them not to be Lawful Evil by valuing the letter of the law over ignoring blatantly twisted laws that push people away from happiness and security."
