Maybe they aren't paying for those courses. They're almost always spending someone else's money (loans feel like free money to kids). So they do not value it.

I bet if someone compared cheaters to students who were working and their wages went into tuition, there'd not be a strong correlation.

Nobody ever asked my GPA after I graduated. My diploma is somewhere in the basement, I've never displayed it and nobody ever asked about it. I attended graduation only to please my parents, who came out for the occasion. I didn't want to buy the class ring, so my dad gave it to me as a gift.

I didn't care about the diploma. I only cared about the education. If I only wanted a diploma, I'd have gone to a much easier university.
