That is because the government give incentives for student doing well. When really a teacher chose to go to college to become a teacher and should not recieve a reward for doing their job other than annual and cost of living raises like the rest of society. The same way the police are given incentives for arrest, drug bust , and guns. it is designed for people not to care at some point which is what I think happened in Georgia... Versus doing their job for they pay check they only did what the needed to do to keep their paycheck ..
