I just want to draw a small amount of attention to Mackenzie Scott. She is the woman who was married to Jeff Bezos, the founder of Amazon. There are some people who are fans of Amazon and I am one of them. I read that Bezos and Scott divorced, and that she got half of his money. Bezos is on and off one of the richest men in the world. Maybe you have read that Bill Gates and his wife also divorced recently. The Pocket reading service offered an article about Mackenzie Scott and what she is doing with some of her money.
You may know that a billion is one thousand millions. Many older people immediately use the word "million" for a handy large number. I used to teach 5th grade arithmetic and one of our tasks was to grasp the size of a million and other large numbers. I made a folder of sheets of paper with dots all over them. The whole set had a million dots. Once in a while a student would sit at a desk and slowly turn page after page of dots to experience a million. Mackenzie Scott has a personal wealth of 55 billion dollars.
She is wisely assisting charities and foundations by giving them a large donation. She hasn't made an overly big deal about her donations. When I ask my friends if they recognize the name Mackenzie Scott, they often do not. https://www.bloomberg.com/graphics/2021-mackenzie-scott-donations/
The linked article is fun to read and to think about. It says that a number of times, a notice of a very large donation has been dismissed as a scam or simply unrecognized for what it was, for a month. The former Mrs. Bill Gates and the former Mrs. Bezos have collaborated some in deciding on donations. As a former professor of education myself, I note that Mackenzie Scott recently remarried, and she married a high school science teacher.
