This is probably true but not an excuse for the perverted behavior and incentives that result. If 90% of the students at Harvard aren’t in the top 10% but feel entitled to be and thus cheating becomes a more attractive solution than taking the medicine of reality - clearly the penalties for cheating aren’t quite high enough.

Penalties don't work when only a few cheats are found.

In this case, the cheat was obvious, but how do you detection enrollment cheats or totally bought research projects? It's not even funny how little you can do here.

Even plain and obvious plagiarism is being missed.
