You have just been put in charge of the world, but you can only make one rule. What is it and what events or experiences led you to it?
If I had the choice to make one rule that would affect the world, I would choose a solution applies to education. It is important for us to realize that an educated society is a prosperous society. If we want the world to flourish, then we have to realize that there are selfish gains and selfless gains towards making the world a better place. We all know that we enjoy doing things that help others regardless of whether or not the directly come back and influence us. For some people, it is not about the gain of one's ego that drives them to do the right thing. That is not the place for education in the traditional sense. When we raise our children, we should be raising them to be the best people they can be and to inspire them to treat other people with respect; that is just a fact of life. The job of the new worldwide education system is this, teach the world how to grow together with other people from other nations. Instead of teaching about how the world differs from one another we can teach how everyone has a place and that there is work that can be done to increase the productivity in the world.
Before the industrial revolution, the human race was in a zero-sum game in terms of resources. We only produced as much as we used. The standards of living were low and the number of educated members of society and also those above the level of poverty were little in comparison to today's standards. We had a limited amount of the global pie to share and it made more sense for us to take others share of the pie as our neighbor's loss was our gain. Once the industrial revolution happened, we had an increased standard of living like no other time in human history. For the first time, we were not in a zero-sum game, we reached the positive sum game. For the first time, we increased the size of our global pie and allowed for more people to have access to more resources. This increased the overall standard of living around the world.
Now, imagine if everyone else in the world had the same access to world-class education like Europe and the United States does in terms of higher education. Instead of having a billion people with some level of higher education, we had a level of up to three or four billion, or even for the hypothetical, six to seven billion, imagine the progress that we could accomplish if we had seven times the funding and seven times the research scientists, philanthropists, entrepreneur, and engineers. How far could the world go if we all had the ability to access education? We are far more beneficial to each other as a species if each other if instead of hotspots of growth and development around the world, there is growth and development everywhere. New teachers, scientists, doctors, farmers, and happier and healthier citizens. It is in all of our interests to both yourself and others that people in regions of the globe that we don't know about are well off. There is a selfish interest, but that does not mean that we shouldn't work to make sure that everyone in the world is well off. If this was a possibility, it would revolutionize our species as a whole.
If I could make one rule, it would be all forms of education, for everybody, everywhere.
