Freedom and Power
Washington D.C. is the worlds most powerful city. It also represents Freedom to billions of people around the world. However, while the powerful and not so powerful both call the city home, they rarely interact on all but the shallowest levels.
I've always been fascinated though by how much freedom the homeless of DC have, especially compared to the sea of mindless bureaucrat and government types who march in from the suburbs every day, rigidly conforming to the dictates of peer pressure and official Washington culture. A member of the political and power class here in Washington risks it all if he were to step out of line, and as a result, is usually forced to endure a life as a stereotype. The homeless, on the other hand, are free to do what they want (and some even make decent money panhandling and busking).
This image in particular struck me as a powerful reminder of the divide as I made my way to EPA.
