Taiwan English schools bribing children

I have been here nearly a year now and I am sure it is just another bribery tactic to get children to learn English. At first I never really paid too much attention to it but I soon realized quickly that the point cards in 1, 2 and 5 denominations are sort of treated as if they are money and the children are just driven by competition to get more for themselves. I have taught in Japan, China and children of all ages from Korea and Vietnam and Taiwan children are by far the worst. I always thought Chinese children were bad but they are not as bad as Taiwan children whom are extremely competitive. I wonder what drives them?
