The "pretty much" disclaimer in their comment covers this case. But it doesn't dispute their idea that most billionaires reached that level of wealth by exploiting others

It depends how you define "exploit". How is Jensen Huang "exploiting" others? He started a GPU company, hires a lot of people, pays some of them very well, pays others not that well. I don't think you can say he is "exploiting" them though. He made lives of hundreds of thousands of people much better. If anything I think he should be celebrated and I am very happy he is a billionaire.

How is Roger Federer exploiting others? He played a competitive game, won a lot of tournaments, accepted a lot of sponsorship money. He is now a billionaire. Did he need to give up ethics and morals to get there? What kind of blame is that really?
