There's no debate that education could use more funding in the country. I live in Utah which has the lowest per capita spent per child in the U.S. You can bet I wish more was spent on education.
But keep in mind that when kids come out of school uneducated it's probably 90% the parents fault for not helping their children and 10% lack of resources at the schools. While school supplies, books, teachers and computers will help kids learn, it's the parents who have to motivate and help their children learn. Throwing money at a problem rarely solves it. It takes time and effort on the parents and childrens part. A motivated kid with ratty 10 year old textbooks will learn more than an unmotivated kid at a private school with a laptop and a teacher with a doctrate.
