That's completely illogical. Legacies are typically going to come from successful, well-educated backgrounds and thrive. If this documentary is any indication, it's that the schools care more about artificial diversity than scholastic competency and students like this are the ones set up to fail when they actually have to perform. And many schools have said or demonstrated exactly that, like Harvard or the entire CA state system.

You can't fix issues in primary education in college unless you're willing to let the whole point of college change from enhancing education to being a poorly-executed social experiment, and the results speak for themselves.
