I don't think the idea of completely destroying the foundations of art is the purpose or idea for anyone. You can't really take that away, even if it is the government.
Art is expendable when compared to the basics 4 in comparison. As others had mentioned, people see the most profitable and numerous professions in the other fields. As i have said in the past post, Art in lower education stages can't really compete with higher up such as college.
Cut em out when you are on a tight budget. They are pretty expendable and if you can't see art in school, than there are plenty of other places to witness it.
Even if Art was completely and totally destroyed forever, don't be bothered by the idea of the human race being turned into mechanical beings. We would have turned into mechanical beings long before that ever happens.
