I'm not claiming education is the ONLY cause or ONLY solution. It's a notable one, though. The topic of how to get a nation with a history of division, built-into-the-very-system racism and an actual civil war fought in large part over this very matter is not something I can easily cover in a single forum post, as it's a topic entire academic papers, studies and books have been written about. One fact to consider is that we are talking about changing how people think, and that will take generations to happen. Any attempt to force people to change their thinking and beliefs in an instant is, as we've seen in the US, liable to cause a major backlash that might get a populist president elected or do some other great harm to the greater society in the end (and hell, I'm saying this as a person who still thinks Trump was better than Clinton by a wide margin). It's a change that happens slowly, over time, as new better educated generations with a better understanding of the world replace the old, and can only be accomplished if the underlying systems of law, justice, education and governance act as a suitable bed for such a change, rather than a system that enforces the old style of thinking.
