An Advanced Civilization on this Planet— Who Needs It?

I’m not sure if we need an advanced civilization, but it might be pretty cool if we had one!  In your mind, what are some of the qualities that would characterize an advanced global civilization?

I suppose an advanced planetary civilization would have a world-wide political and economic order of some kind, a “world government,” if you will.  Some people are afraid that this would mean a tyrannical world-wide  oligarchy that oppresses the masses for its own benefit.  But it might mean a system that recognizes and tries to protect the rights of everyone.  The UN’s Universal Declaration of Human Rights  might be a basis on which to build such a system.
