"...study after study shows that the sooner a child begins learning, the better he or she does down the road. But today, fewer than three in ten 4-year-olds are enrolled in a high-quality preschool program. Most middle-class parents can't afford a few hundred bucks a week for private preschool. And for poor kids who need help the most, this lack of access to preschool education can shadow them for the rest of their lives. So, tonight, I propose working with states to make high-quality preschool available to every single child in America."
