In Chicago, there's this man named Theaster Gates. He did something really awesome.
When the recession hit, he decided he'd do something about it. He bought up a bunch of run-down buildings on his street, disassembled parts of them, and used those parts to make cool art (ie. a front porch swing made of a door frame). He then renovated all of these houses to be cool public things like libraries, and cafes. Mr. Gates wasn't some big name artists, he was a young man who decided to use his love of art to change the word around him. Now, international museums exhibit his work, and his installations sell for over a million big ones.
I think we could all learn a thing or two from this guy.
