Commented on something related in another thread, but it was either Bierce or Shaw who said something along the lines of, "all professions are a conspiracy against the layman."
This is distinct from trades and arts, where there is a simple scale of competence.
The reason most jobs demand a university degree today is because of the professionalization of management and HR means that the people making hiring decisions have a direct interest in preserving and increasing the value of their own positions and credentials.
For example, have fun getting P&L responsibility or significant direct reports without a degree, let alone getting a work visa. The reason for this is not because of competence, it is because of a tribal identity that the schools inculcate.
The thing about "uneducated," people is that because they have to trade on their skills and performance, and not credentials, over a certain intelligence you can't trust them to sustain cognitive dissonance (or to lie) on behalf of the team, because they will defect if they perceive risk to their competence-based identity.
When you hear someone say an uneducated person "doesn't get it," they are not referring to competence, they are referring to recognition of a power dynamic that means success and group survival is about relationships and the perceptions that drive them, and not about the material quality of the work.
This may sound nihilistic and cynical, but recognizing non-technical education credentials as more of a tribal membership or a kind of managerial officer training than a signifier of skill clarifies the dynamics of companies and organizations, and could save a lot of stress wondering if people are evil or insane.
They aren't necessarily evil or insane, they are indexed on perceptions and relationships that are not decided only by skill and competence.
Few will articulate it this way, but there is no incentive for people with an education to criticize it, and without one the perspectives and tools to do so are rare.
