Well the proof is in..... they don’t learn anything!
These misguided malcontents can send their diplomas back however, I can only assume that University will keep them on their rolls. Why? Because universities depend on their rolls to substantiate enrollment and GPA for future enrollees who ascertain the worth of the University they are choosing to attend.
Basically what the misinformed are thinking is if they are returning a piece of paper for the University to put in the trash can the record of attendance and studies will also be expunged. Yet their diplomas are still recorded and their GPA will still be retained on file and will remain so.
Accountability. Perhaps a business degree would have given the clueless a better understanding of how management functions.
