Thank you for the comment. It is not meant as a comparison in the sense that all developing countries can easily become just like the egalitarian high income countries of Europe over night. As you say, high performing countries such as Denmark or Norway in our example are aspirational examples. The real work as you say is to focus on the real needs of children in the early years. These are truly foundation years for children, and what they learn early in their schooling years will serve them well going forward. Developing and middle income countries are taking the right steps. As you say, they need to accelerate the process and reach as many children as possible with a high quality education early in life.
