I think the point is more like:

It's hard to imagine a recent college graduate understanding the machinations of corporate entities enough to give meaningful advice about how to run more "efficiently". It's a bit like when a SV company is promising to revolutionize farm equipment and the founders have no background in agriculture - weirder things have happened, sure, but you can see why people are a bit skeptical.

Yes, it's obviously a bit unfair because sometimes untainted eyes can be the most beneficial, but hopefully you can also see why there's a bit of skepticism.
