If someone adds value to the world, but does so through exploitation of the workforce, scamming their customers, or tax evasion. They didn't actually add anything to the world. They are net negative.

That’s an argument for the product, but the system still promotes shitheads to the heads of the companies that deliver said products.

And that still means shitheads are shitheads, regardless of the amount of money they have.

Net negative matters.

I could, for example, kill every animal in the forest then claim how good it is that the plants grew so much that year without so many things eating them. In the long run, it's very negative however.

Same for billionaires. You could say how great it is that we have electric cars, but who gets hurt and could it have been done without harm to people or society?
