I, most definitely, believe you are clueless on what cheating was actually happening under your nose.
As a student, I saw what you couldn't.
Dude, with all due respect - our people didn’t need to cheat . Getting straight 4.0 in class work was incidental to their primary job as research scientists defining the state of the art.
I used to go through a stack of applications for students who never got a B in their entire academic careers, and had perfect scores on their SAT and GRE entrance exams plus some pretty amazing extra curricular skills
They all went on to pretty amazing and productive careers. The foreigners who stayed in the US we’re all disproportionately successful individuals who made their marks in their chosen fields
