What brought me to do something similar in a former job was, that I realized it only hurts my coworkers when I do more than the average. The management would say to everyone with performance below average something like: "How can we help you to improve your performance? What do you plan to improve your performance?" The result was that most people stopped working once they reached their goals because otherwise they would only increase the average^^ I read a lot during this job xD
