Humanity has advanced because of technology and cooperation. Biologically, however, we are not much different than our ancestors 50k-years ago. At that time, we were organized into tribes of 50 to 200 individuals that shared technology and resources with all the tribe; the crippled, the old, the dim-witted.
Today, the entire world is connected and should be working as one tribe, but even though trade is globalized, sharing is not. The rules have been written by the already-rich for their own benefit, resulting in an unsustainable disparity. Empty mansions and parked private jets are evidence of wealth extraction, NOT wealth creation. We have to globalize tax laws as well as trade rules.
