So this version of the argument basically amounts to: people who have harmed society should contribute to social welfare that bolsters the economy and society collectively. Which while a solid effort and earning my upvote, 1) the_petty_auntie’s reply doesn’t show signs of making this particular argument and 2) in this particular case, it fails because society as a whole wasn’t harmed by her son’s actions - rather a particular victim was. And as the victim was a teen at the time of the incident, it’s unlikely that the victim would be able to take advantage of student loan forgiveness unless it happened many years ago.
