Making the rich richer isn't necessarily the point, but it is an unavoidable consequence.
> Capitalism is about producing stuff.
Humans have been producing stuff well before the concept of ownership was invented, and certainly well before the massive wealth accumulation that is the hallmark of capitalism.
If the goal is to reduce poverty, I fail to see how the existence of billionaires is a positive outcome, either now, in the form of Musk and his ilk; in the form of the robber barons of the late 18th century; or in the form of the noble lords of the feudal period to owned a lot but contributed nothing.
Regarding the idea that we can design a system where "no one should be left wanting," that sounds nice. So does big rock candy mountain. There is no such system.
Great, but it doesn't. The gap between the poor and the wealthy has only grown in the US, especially since Reagan's "trickle down" economics.

The accusations against the working poor of "envy" are a barbaric slur. People just want to get valued fairly.
If the goal is to reduce poverty, the number of billionaire is actually irelevant. How you fund reducing poverty might influence the number of billionaires, but, for me it is more important what each society does for the poor, rather than counting how many are billionaires today.
