This is emotional pleading, not a serious argument of any sort, based on the core premise of "this person has more money than me, and I don't like that, therefore I should get some".
Wealth and income inequality has well-studied negative effects on society.
The ability for a single person to own over $100m in assets is not a human right. It's not a protected class or status. It's an abhorrent misappropriation of human resources. It is a societal mistake.
And let's not forget, people like Elon Musk, Jeff Bezos, and Mark Zuckerberg have multiple THOUSANDS of $100 million dollars in net worth. This completely insane $100 million figure is so small to those men that you would have to earn $100 million every single year for over 30 lifetimes to get to their level of wealth.
It's not about demanding some of the money from the wealthy. That's a shallow way to think about it. It's about the inherent power imbalance and exploitation that comes along with being excessively wealthy like this.
Think for a second what would happen to you if Jeff Bezos banned you from using all Amazon products. Would the Internet even work anymore for you? You know, every company has the right to refuse service to anyone. This one man can basically cut you off from television, e-commerce, Internet, employment (if you do engineering work on AWS), even Thursday Night Football.
