In some countries it's pretty normal and expected for students to cheat in school, but after they find a job where they are treated with trust and respect and given real-world problems to solve, absolute majority will stop playing tricks.
If you have to cheat to design model airplanes, you have no business designing real ones.
The point is, they don't care at all about the academic problems because it's (a) not interesting to them and (b) usually professors don't motivate students with real-life examples. E.g. while microeconomics is very much relevant for everyone, the way it was taught to us, it felt insanely boring and inapplicable to real problems.
