I can't speak for college, but I cheated quite a lot in high school. I cheated "better" than the students in this post though, by copying sentence by sentence from various sources, rewriting it to make the cheating non-detectable, and reading over it to make sure the flow was good. It saved me at least 50% of the time compared to writing something from scratch, and the quality was good too.
Do I feel bad about it? Absolutely not.
It's imporant to consider why people cheat before you deem it bad. I cheated because the assignments were a waste of time. Plain and simple, a waste of time. It often felt like something the teacher gave us just so we shouldn't spend our evenings having fun. It wasn't something you were supposed to learn something from, it was something you were supposed to do because you were supposed to do it.
I should point out that that the Norwegian high school system is quite different from the American system. We couldn't choose our subjects, we had to take what the education law said we had to learn. Because of that I had a lot of subjects that I didn't have any interest in whatsoever, the only thing important was the grade I got. When you don't have any reason to study a subject other than to get a high number on a paper, it's natural to cheat. It's borderline impossible to be motivated to do something forced on you.
However, if the subject or course is your own choice, like the case with most university courses, cheating is something different. If the the only value the students get from a class is a grade and not relevant and valuable knowledge, I understand and sympathize with the cheaters.
