The point of school (American school, at least) isnt to learn, its to get a good grade. When the goal is a number, than 'cheating' is simply trying to achieve the goal.
If the goal was to actually learn, the "cheating" that you see in schools would become "collaboration" - much like in a workplace with quotas and ridiculous metrics, people will cheat the system - in a workplace who values output quality first, you end up with collaboration between employees to reach that goal...
The problem is - 90% of us went through the school indoctrination of "the grade is the goal" ... and carry a lot of that mentality out into the work force.. and at worse, many of them start companies and align their business goals for their employees with that same standard..
