Parents on welfare are more likely to need the incentives to take on the costs of sending children to school.  Parents on welfare benefits are the most likely to need the extra inducements. They generally tend to be less educated and oftentimes be less appreciative of the long-term value of education. In the late 90's, 42% of people on welfare had less than a high school education, and another 42% had finished high school, but had not attended college in the US. Therefore they need the additional and more tangible, financial reasons to send their children to school. Children living in poverty in the US are 6.8 times more likely to have experienced child abuse and neglect1. While attendance might not be a sufficient condition for academic success, it is certainly a necessary one, and the very first step toward it. Some parents might be tempted to look at the short-term costs and benefits. Sending a child to school might be an opportunity cost for the parents as lost labor inside or outside the homes (especially in the third world) the household, or as an actual cost, as paying for things like supplies, uniforms or transportation can be expensive. Around the world there are an estimated 158 million working children, who often need to work to contribute to their family's livelihood2. In the UK it is estimated that sending a child to public school costs up to 1,200 pounds a year. If they lose money by not sending children to school, this would tilt the cost-benefits balance in favor of school attendance. 1 Duncan, Greg and Brooks-Gunn, Jeanne (2000), "Family Poverty, Welfare Reform, and Child Development", Child Development, [Accessed July 21, 2011] 2  [Accessed July 13, 2011].
