People getting richer doesn’t automatically make someone else poorer. The total amount of resources the human species has access to is constantly growing as our productive power increases. In fact, most of the time the total productive power increase is directly linked to someone getting richer.

Wealth doesn’t generate itself, and no human can generate a billion dollars in value alone, even by working 170-hour weeks.

Sure they can. J.K. Rowling is a billionaire. How many people did she exploit by writing 7 books? The people who worked on the trains or in the coffee shops she hung around and bought coffee from? The idea that people only collect wealth by depriving someone else of it is a pre-modern understanding. Same with the idea that value is related to hours worked.
