Good freewrite. I would add that preserving what people have is the motivation to not wanting free immigration from everywhere. With 8 billion people on the Earth, the threat of having more people competing for food, money, housing, happiness, and safety causes people to want to create a system that ensures people have rules that need to be followed to freely go to a new country. I think people are generally good, but when they are confronted with threats, they behave defensively. I am not a billionaire, but rich people don't know what to do with the massive wealth that they have. They don't want to give so much away that their ancestors will not be advantaged and they want to find the best way to invest what they have. We all differ in how we spend our own finances in the same way to some degree. Hopefully the billionaires of the world will see that the best way to spend their wealth is to give most of it away. Whether it be in funding science, scholarships, buying someone a Bitcoin, or feeding the poor, it will be better used doing something rather than sitting dormant.
