Politicians - Regarding 2018:
If taxing the Rich is not the cornerstone of your platform, you are part of the problem, not the solution.
Yes, common human developmental disorders such as racism and greed need to be addressed, but these are distractions from endemic systematic exploitation by the Rich, who consider everything and everyone as resources they are entitled to exploit, and who want us distracted by the chaos and insecurity they foment.
When government does its job, which is to protect us from the Rich and invest in things we need that don't create instant profits for the Rich, such as education and infrastructure jobs, the factors that exacerbate competing interests and adversarial relationships will abate.
At the core of it all, there is only one problem and only one solution worldwide. Tax the Rich, and everything else will fall into place from there.
