People love to believe comfortable myths. For a certain group of people, their comfortable myth is that wealth inequality can be solved by education. It cannot. People become wealthy because of luck. Who your parents are is luck. Where you were born is luck. Your intelligence and physical and mental health are luck. It's all luck. The best schooling in the world can't move this needle much, and its power grows ever weaker as technology and automation eat more and more of the economy.
"Growth" can't save us either. We cannot escape by giving the economy more gas, because the faster the economy goes, the more things get automated, the more jobs vanish, and more wealth gets concentrated. We are rapidly approaching a point where a tiny fraction of the population controls almost all economic activity, and in that future, the only way to fix wealth inequality is to tax that group and spread the money around. Most of that group do not want this to happen of course, and they get to make the decisions. But sooner or later, this will become an untenable position.
