„An early learning gap is already apparent when looking at four- and five-year-old children. In the United States, children with poorly educated parents lag significantly behind in reading and mathematics in comparison to their peers with highly educated parents. A similar pattern, though to a much lesser degree, exists in Australia, Canada and the UK.“
