The 19th century was a century of empires, the 20th century was a century of nation states. The 21st century will be a century of cities.
I think the Occupy movement is absolutely fantastic; in my opinion, it's probably one of the most important people's movements of the 21st century and the 20th century. The trouble is that nobody really wants to support what they represent. They are too 'grassroots' for their own good.
