There you go again posting the usual Fake News / Shibai. 

What you willfully failed to understand is the study was put out by the educational bureaucracy. The outcome was already set before the study was done. Spinning the educational bureaucracy and its money pit pension as "win - win" when we know it is a pack of lies.

Only if multiple outside sources with absolutely no connection to education repeat the study and get the same results can it be considered fake news.

Saying "preschool program returned to the public an estimated $7.16 for every dollar spent" is like saying rail will pay for itself. Clearly a complete oxymoron.
