A reasonable proposition. But not necessarily a correct one.
The Yale entering class may well be superior to Hillsdale's. But what comes out four years later is, on average, probably less educated.
But it's a sterile argument. You are never "hiring the class", you're hiring the individual. In that regard, I've had equal success with undergraduates from Princeton...and Bradley...and Oklahoma State.
My own experience was better with Princeton. I specifically remember the (Princeton grad) girl I hired asking why I hired her a year afterward considering that she had no experience doing what I hired her to do. I told her that I felt anyone who was reasonably smart could do what I wanted her to do and in her case, at least, I was correct.
As a geezer now, I sometimes take classes at two top level schools, one an Ivy. The classes I take are all real academic stuff (no xyz-"studies") and I can tell you that the level of the kids I encounter is pretty top drawer. I have a small state school near me. I've never taken classes there but the books they assign for their courses are mostly very low level.
