Aboriginal Art: Where did the money go?

There is this article on Aboriginal Art in Telegraph (UK). Having been to some of the remote art centers in the outback of Australia, we really appreciate the article. It has an brief overview of contemporary Aboriginal art movement including the key events since the 70s'. It also exposes many underlying problems with the Aboriginal society and the well-being of the artists.
