If children are paid for better grades, they will want to do better in school. We don't have to pay children for D's and F's, this is rewards for GOOD GRADES, not just for being at school. When students are paid for good grades, they learn that working hard and making good choices does have its rewards. They will try to make better grades, in the hopes of earning more money. Children will also learn responsibility and the value of money; rather than just begging Mom and Dad for all the toys and video games they want, they will work harder and save up for their next purchase. Moreover, many schools have fundraisers for various charities and projects. Rather than dragging Mom across the neighborhood to sell cookies and making Dad bug his coworkers to buy chocolates, the students will buy these on their own, and help the school itself.
Kids would be smarter because they want money. Kids these days don't listen to teachers because they believe it is a waste of time but if they get paid for good grades, they would listen and they would be smarter. They would also have a better chance at having a good job. If kids get money for good grades, they would have a better chance of getting a good college education. It would be easier for teachers to teach because the students would know that if they did not listen, they would not get any money. Also, kids would not be tardy because if they missed anything, they may not receive a good grade.
