I'm not trying to be flippant, this is an actual question.
Sure, getting a higher degree at another institution will have that requirement, as would a professional certification (medicine, law, professional engineering), but those are relatively narrow scopes.
Isn't it true that in most cases nobody is going to care or even know enough to check accreditation?
You don’t want someone designing a bridge, performing open heart surgery, or flying a plane with 300 people on it who were trained by unverified schools.
The risk tolerance varies a lot between people.
It’s the same concept as “regulations are written in blood.”
Getting a pilot's license requires a certain number of hours of flight experience, which one gets as a student.
No state issues a medical license without completing an accredited residency program.
It is completely absurd we have not built an alternative, online liberal arts 4 year degree that basically cost nothing.
There is absolutely no reason this could not be done for less than $1k a year right now.
I suspect a large reason is because the people who benefit from the cartel, basically every professional educator, like things as is. The massive education inflation cost is a feature for the cartel, not a bug.
