A cheater won't get far in technical profession anyway

Sadly, I have far too much personal experience to the contrary. I used to work for someone who was a "cheater" to the extreme. He was an RF engineer whose designs for RF compenent systems only worked because he had technicians that re-worked his designs until they worked. He would then fault the techies when his designs were unworkable.

My experience with the man directly was that he would take credit for my work directly. (I designed/built automated test systems for him) He would tell upper management that he designed the systems and wrote the software and that I didn't know what I was doing.

He was found out the day we got a new VP who could see through his BS and he couldn't explain how one of the test systems I built worked to the VPs satisfaction. The VP then asked me and I gave him the correct answers.

the responsibility of catching a cheater lays squarely on the teacher at school and the school system.

This is why there are now ethics classes in schools. Seems that cheating is considered by our society as being OK as long as you don't get caught. Unfortunately for my students using Perl Monks to cheat with was not an option since I made it clear to them that I monitor Perl Monks as well as several other online communities.
