Even if you divided up all of the money equally today, that chart would eventually look the same again.
Yep.
If you want real change, then what's really needed is not a change in economics, but a change in what it means to be a human. A change in mindset.
The current mainstream image of what it means to be a human is to consume outrageously, to breed with no responsibility, and to abuse your freedoms (I won't argue with the people who say we have no freedom. Freedom is a privilege that you have to earn.). Thus, mankind is settling with these results.
What is needed is a newer form of education that teaches, without fear, what it means to be a human, and what each individual's innate strengths and weaknesses are (there have already been breakthroughs in Russia about how each individual mind works, each psyche of 16 psychological types having its unique strengths and weaknesses, and I've discussed the topic of Socionics and Myers Briggs here before), and to utilize our resources to help each other and to further mankind.
And with this, we will have derived an ethical framework of what it means to be human. A framework that one can look at, and not disagree with.
We are all vessels of meat, and we can see outside of ourselves through the tool of mind. We're all little pieces of the universe. We are all one.
Of course, we don't live in this type of society today where logical choices preside over primitive choices. We live in a society of mediocrity. Right now everyone is trying to take as much as they can from this Earth. However, I believe we will live in this type of society someday (but not in our lifetimes). What's first needed is a scientific breakthrough in acquiring a nearly limitless source of energy so that we don't have to quibble over economic inefficiencies caused by lack of energy sources (Usable fusion energy must replace oil, but let's be honest, that change won't come in our lifetimes, just as the teaching in schools of how to use your psyche to its maximum potential and not to waste your primary function of intuition on flipping burgers also wont be taught in schools anytime near our lifetimes).
And that's enough of my optimism for the future. Back to making the most of what I have in our current reality.
