So your solution for the system failing a person is to punish the person but reward the powerful people engaged in the bad behavior. The ones who brainwashed the kids into thinking that this is what they're supposed to do.
People have agency. The system didn't fail a person. That framing completely ignores their actions. Especially for paying so little on their loans and complaining about it. 18 year olds can vote. If we trust them with that, surely they can be responsible for their own choices.
Moreover, they said the accreditation of both institutions should be investigated.
Not so. The consideration should include the fact that when a child has been spawn camped by school, family and society at large to implant the idea that tertiary education is required to participate in society and without a degree one amounts to nothing, as is often the case, then it indeed is a failure of systematic nature and it would be not fair to put the blame on the now young adult's shoulders alone.
Similarly, the person with the credential that says they can do basic math that cannot do basic math should not have the credential.
