Nobody complains that requiring a bachelor's degree is "educationism" because that would be silly, must like this "lookism" tomfoolery.
Actually I do complain about that... silly or not (though I don't use that torturous word you just made up) - I call it classism. There are certainly times when a bach. degree could be considered a genuine job requirement, but it actually annoys me to no end when employers make having a degree (but they don't care in what!) a job requirement.
If it is a job working at a nature center and leading kids on tours of a marsh, sure, require a bachelors in environmental studies or biology or some related science. I can get that. But it is silly to hire someone who has a degree in women's studies over someone who doesn't have a degree but has been an avid birder for decades and can quote from the origin of species from memory. Just because it isn't illegal doesn't mean it isn't discrimination.
I link it to classism because the biggest barrier to school is not motivation, nor intelligence but money. It is wrong to give employers a free pass to hire people simply because their parents could afford to subsidize a useless degree so they could apply for jobs that require you to have completed a degree, any one at all.
I don't blame employers necessarily for using education as a "shortcut" to try to guess whether a person has some sort of basic modicum of brainpower - but I think it flies in the face of the so-called American dream of class mobility if we justify using unrelated credentials to weed people out of the candidate pool.
Not to mention that because a bach. degree is the new high school diploma, I seem to be seeing more and more people with higher and higher degrees who can't write a sentence, let alone a paragraph.
I am definitely biased here, as someone who doesn't have a degree (couldn't afford to finish it) - but was lucky enough to find an employer who didn't discriminate against me on that basis.
