I donāt think anyone uses āvaluableā in that way. Saying āthe most valuable cars are owned by Jeff Bezosā doesnāt mean that in-aggregate all of his cars are more valuable than other peopleās cars. It means that the individual cars that Jeff Bezos owns are more valuable than other cars.
I think there might be a confusion here. Your claim is that the dollars we own are more valuable per dollar
But the post is referring to the overall amount of dollars. Eg Jeff Bezos dollars might be more valuable than mine.
