"There is an increasing body of research indicating that the quality of the care a child receives from birth, as well as the safety of socio-cultural environment a child is born into (which can be controlled by high quality child care), are strongly correlated with how productive a member of society the child grows up to be."

Can you please cite these research results. There are some specific results, but I would be interested in your long term data.
