You are badly misinformed. Indentured servitude is a contract to serve for a fixed term in exchange for large up-front compensation. It is not a financial debt but a performance obligation, and cannot be inherited.
I have stated my source in another comment. Indentured servitude is of course used a various points in history to refer to different things. But I am not "badly misinformed" - I have read a decent amount about modern day slavery, if you believe me to be wrong, please state a source. Mine, as stated above, was a book on slavery by the head of the "Free the Slaves" organization.
You are nonetheless mistaken. If "indentured servitude" is being used in that way, it is being misused as a tool of the slaveholders to whitewash their actions. By joining them in that misuse, you have conceded your own mind and become a willing collaborator. This matters: tyrants gain power by controlling minds, not bodies.
You misunderstand me. I am not whitewashing anything. Indentured servitude is slavery. It describes one particular form of slavery, common in some parts of the world. I don't know where you get the idea that I'm saying it is tolerable or OK.
What I am saying is that college debt from middle class 1st world adults is not indentured servitude.
