There are some good photographs there for sure. Without an overview of the situation these photographs were taken, it's a little confusing understanding the context. Some people look like they're part of the occupy movement, others just look homeless.
I lived in Portland for over 21 years when I moved outside the US three years ago. Looking at these pictures is depressing. A country with so many resources and potential, yet so many people throwing their lives away. Not a lot of these people appear to be truly disabled or incapable of taking care of themselves.
Asking for change is apparently the hip and cool alternative lifestyle. The guy with the $$$ for weed sign is particularly pathetic.
I travel around the world and very often see people who are truly between a rock and a hard place. I travel where the struggle for daily bread amounts to a mountain of blood and sweat compared to a person sitting on the sidewalk, practicing 'hobo chic' with a banjo. It seems like a costume party more than anything else.
Thanks for sharing the photographs. They really made me think about where I've been and where I am now, not really feeling a need to come back.
