That really depends on what you want the civilization to look like. And what I want to see is not going to be what you want to see, so we have to find a way to come together and decide that number together.  I think the biggest problem is the difference between governance and government. We need governance models that are built into the systems, and don't have to employ millions of people to push paper and run calculators.

Right now the global government expenditure vs. GDP ratio is around 46.3%.  That is INSANELY HIGH.  But it's also built on a fiat monetary system where we can't trust any of the numbers because they are not real numbers.  Our ability to trust each other across the world seems from the media noise like it's at an all time low. But unless all governments just switch over to Bitcoin on January 1st and we see what happens, nothing is really going to change.
