There can be more than one assumption carried so why not judge each on their merits instead. Taking this other line of thought, it could definitely be truer in a vocational college or work placement type education but less so in a typical college education. Traditional college doesn't even come with the assumption you'll ever leave academia to go out into "the real world" to make your living, or that you have an actionable goal beyond being interested in the first place, let alone the assumption it should be the only goal ever considered. An easy way to see this take is not the actual primary goal of college is the self-apparent conflict of such activity being seen as underhanded in the first place.

Even if we took this line of thought as the truth though, also came to an agreement this is the most valuable skill of all to teach, and also took it as being universally good to do regardless of context, what's the reasoning for assuming college only seeks to teach and grade success on a single skill in the first place?
