The problem is not limited to Australia, I am afraid. It is the whole western society, to guess the least. And I believe it is not a matter of pure choice. It is systematic calculation, systematic deletion of things which allow people to think autonomously. Remember stories where regnants would forbid writing because they did not want the truth to spread? We are not that far from that, me thinks.
The media pushes chicken and beef because it is something that can be sold by Somebody else. They would quite never put on something you can't buy. Plus, art is something that makes people self-conscient.. Would that regnant allow such a thing?
