A person with a single dollar to their name will have a higher net worth than a significant fraction of the world. I have never found "more wealth than" to be a useful relation to think about.
You're talking about millions of people who have so much less than nothing that they will have to work for years just to get to $0.
With all our technology, our wealth, our sophistication; all the work of our ancestors and the sacrifices they made, all the works and understandings they developed, and the ability to transmit this knowledge at the speed of light and for damn near free; with the incredible bounties of the earth, the ocean, the sun, plants, animals, fungi - with all that, why should so many people be in such a hole, working their arses off as they make wealthy people wealthier?
While you may feel privileged to have a single dollar to your name, 8 people have more dollars than 3.5 billion people. That points to real, catastrophic injustice endemic in our systems and societies, even our belief systems.
