suppose it’s true. Here’s what the authors say:
Our results indicate that college administrators face an important trade-off when they consider policies designed to limit fraternity life on campus: while such policies may significantly raise academic performance, these gains may come at a significant cost in terms of expected future income for their graduates.
I’d argue exactly the opposite: ... Allow me to reframe the authors’ conclusion:
Our results provide empirical evidence that fraternities are just another way for social elites to keep themselves at the top regardless of actual performance. Those rejected by fraternities, even though they have higher GPAs, earn 36 percent less than those accepted by fraternities. This is further evidence, if any were needed, that college administrators face few trade-offs when they consider policies designed to limit fraternity life on campus.
