I am working on a new book as well. The topic is great government. Yes, some may think governments are problems but they ignore the fact that governments all over the world have been centrally engaged in making great things happen.
One example is the city of Medellin, in Colombia. In 2001 it had one of the highest murder rate in the world (at around 130 per 100,000 people). Some called it "Fallujah before Fallujah was Fallujah". By 2007 the murder rate was down to about 25 per 100,000. Wow.
Great government is credited with this, and the Mayor Sergio Fajardo is commonly seen as the central figure the story. It has been called a miracle (or at least half miracle) in the Washington Post (http://www.concordmonitor.com/article/medellins-urban-miracle?page=full) and by people like Frank Fukuyama (http://www.foreignpolicy.com/articles/2011/04/25/half_a_miracle).
Today I met briefly with Fajardo (currently the Governor of Antioquia) to ask how this happened. He is a really interesting man and was overly generous with his time. I am really excited to see how the story unfolds as I learn more. (below is a photo of the Governor and I at Harvard's Center for International Development).
I am interested in readers sharing the 'miracles' they have seen governments engaged in...
