As I've noted elsewhere in this thread, you do it by making the cost of not correcting it devastating. The only way to change the cost benefit analysis is to sanction the university severly. The death penalty should be a part of that equation.
It won't make any difference.
The university is not athletics, first of all. Secondly, even the proper procedures in place for the future (s they've now been implemented at PSU and also other schools) won't prevent it simply because there's always a balance with worker's rights. Cost benefit? Universities are routinely sued by employees. No matter the costs of paying the victims, it's hard to believe they will impact future administrators.
The one thing we know, there is no gray area when it comes to child abuse. Rules have been changed now and everyone must report to campus police. Now, that's doesn't mean people are criminally liable because one must be a mandatory reporter. But it does mean people can be sanctioned in the workplace. I suppose for universities, it's a good thing that there are relatively few minors around campus other than in daycare, because if that new rule were applied, say, to the student body, you can bet that the school would lose more money in civil suits by applying the rule than by keeping current regulations. This is precisely why schools have changed the rules to only treat allegations of child abuse.
As a teacher, I think it's a shame that the money to pay the victims ISN'T going to come out of the athletics department.
It should. But instead, it's going to come out of the pockets of students through tuition. It can't come out of the endowment for legal reasons, nor out of the research budget. It has to come out of tuition. But if there were somehow a way to take it out of football, I would be for it.
Someone would have to explain how such a plan would work. Maybe cap coaches pay for a long time (decade or more)? Maybe cut recruiting? You'd have to look at the budget.
