What happened in New Jersey was that Mark was naive.
Naive to think that the NJ teachers union would tolerate giving up even an inch of power to promote a public good? Where is the article lambasting the educators over the tremendous loss to the children of NJ because of a fight to control money they didn't earn?
Any accounts of what happened? This used a whole lot of words to say almost nothing. It basically says it didn't work, but didn't go into any details of why beyond a high level complaint about beurocracy
What exactly happened? From what I hear the money wasn't misused, it just didn't fix things.
In short: Through the Oprah show, Mark donated 100 Million USD to the Newarks Schools to improve education. The end result, however, was the opposite. The students ended up being in a worse position due to corruption and mismanagement within Newarks' Schools abusing the capital injection.
