ROI is kinda useless in this context. i.e., they're essentially saying, if the uni is very selective (e.g. Harvard), the ROI is similar to say a state college.

ROI is kinda useless in this context. i.e., they're essentially saying, if the uni is very selective (e.g. Harvard), the ROI is similar to say a state college. But they're disregarding that Harvard, whoever subsidises you, is a $100k investment or w/e, and state colleges are $10k. Just making up ballpark numbers here. Now the ROI might be the same, i.e. they might both end up earning roughly 1.5x their investment in annual salary. But seen this way, everyone appreciates there's a gigantic difference in where you study, even though percent wise the ROI is exactly the same.
