> That is often given as an excuse for this common experience, but it is not really intended. Top schools are assessed on their graduation rates. It is part of the rankings they are obsessed with. It serves no one--students or schools--for students to be weeded out in these intro courses.

Unless I misunderstand what you're saying here, it really is intended. "Top schools are assessed on their graduation rates" so if they don't admit students that will not graduate from the major into the major in the first place, they improve their graduation rates. Therefore, it does serve the school. And it probably serves the student too, since they only spend a quarter or two getting weeded out, rather than a few years and then hit a dead end.
