I am a working artist. It IS what I do for a living. I went to art school and studied art history. No one can make judgements about other peoples artwork without studying the reasons why they make the work they do. You have to spend a little time analyzing and getting into the head of the artist before you can make judgements about the content of their work. Go online, go to his website and read about his work.
Christo's work is all about community. The scale in which he works proves this. I've been in the same room with Christo while he discussed with the public his plans to "wrap" the Arkansas River in Colorado with fabric. He self funds all of his work and he hires hundreds of workers from the community where he works to help construct his pieces. No one is a volunteer. It takes years and sometimes decades to see his work through to completion and the red-tape to get his works approved is all part of his art. Once through that process, the fun begins orchestrating all of his workers and getting everyone involved. It really is a community building event for those fortunate to have one of his temporary pieces in their backyard.
Sorry to rant but I've seen this thread come up every time and I just have to defend my craft.
Here's my website, have a look just to prove that it IS my day job.
