Universities should be more than toll gates

I agree with your general assessment, but not sure if the blame could be placed on employers mostly/entirely. They're also limited by bounded rationality and cannot (or should not) dictate what the purpose of an education should be. There's such diffusal of accountability that no one is really designing the system, just reacting to it. To your point, the system just do what it does. The ultimate unaccountability machine, per Dan Davies [1].

I think we're witnessing the collapse of the university value proposition. In the decades post WW2, the attendance/competition within universities was quite modest compared to today. Relatively fewer people went, and it was essentially a social class sorter, with a liberal education sprinkled throughout. This actually creates a better learning environment, as once you're "in", you can focus on the experience. Nowadays, the university is just another hamster wheel in the grind, in a never-ending arms race against the sea of other students/degrees/credentials. Failure to deliver results means you didn't consume enough, and must consume more. Eventually this dilutes the value of the degree, both from a signaling and a financial perspective. It seems like we're in the peak enshitification stage of higher ed.

For employers, requiring a degree doesn't cost them anything. So they're happy to keep piling on the requirements. I guess the question is what type of employers would actually be the first to decouple their recruiting/hiring from credentialism and rely on other metrics of competency?

You are correct, but the fact that employers are being rational doesn't make them blameless. To answer your question is that I don't see any employers decoupling from credentialism because why would they? So I think any solution to that would require there has to be a cost associated with university requirements for job positions. A fee maybe? Unless the job legally requires the credential (e.g. engineer, lawyer, nurse, etc.), then any other position you have to pay a fee to include that requirement? I know, not great, but what else could be done?

But this is just a tacit admission that a lot of jobs need the credential.

And it's a slippery slope. Should, for instance, a chemist have the credential? It's easy to say, "No". Until you get another Bhopal.

Basically you would start getting more and more fields demanding credentials for liability purposes over time. Some would be entirely justified, like chemist and biologist. Some would be tenuous in the extreme, like c# or javascript monkey.

It's an interesting conundrum, where everyone knows the system is bs but no one wants to take the first step. Hypothetically, some possible scenarios:

1) An external event, like a war, that stress test the credentials and to force selection based on outcomes. 2) Some sort of monetary benefit for employers, like extended internships for high schoolers. Assuming it's cheaper/more effective for an employer to train their workforce from scratch than pay the full salary of a recent grad. 3) A new field, where credentials haven't been established yet.

There are obv caveats to all of these. And they don't address the question of what a formal education is supposed to accomplish. At some point, it was supposed to be to train "better citizens". And that shouldn't be dictated by employers, imo. But nowadays it seems like the purpose is to get a job and survive.

There are absolutely jobs that require credentials and for good reasons that I fully support. I'm not talking about these jobs. It's the ones that require a credential, but the job duties do not involve the skillsets associated with that credential. An easy way to spot these is if the requirement is something like a 'bachelors degree'. Doesn't matter what field, you just have to have gone to university. This is BS requirement.
