Thank you so much Greg for the response. It is an interesting topic and I really like the point Mark Treadwell had to make. Esterman’s comparison in his post is with ‘privilage’. The renaissance was funded by the rich. Esterman suggested that with so much access to so many now that it is (or should not be) a privileged thing.
What I think is interesting about each of the examples that I provided is that each had a vision that was built over time. I would be interested in the schools you mentioned in your post, whether their is a correlation with this. Ironically, with such fast paced change the one essential ingredient maybe stability in regards to leadership.
