As it was written, though, no basis was provided. The opinion was congruent with that of people who believe economics is zero-sum, which is what I inferred you meant from "shitty means".

As for me, although I've personally met Steve Ballmer, Bill Gates, and Paul Allen, I hardly know them. I have read their biographies, and the biographies of many American billionaires, and would not agree that any of them came by their wealth through "shitty means".

The term "shitty means" isn't exactly an economic term, and I'd be curious what you mean more specifically. I'll start by saying an ethical way to become a billionaire is by providing a product or service that people are happy to pay for. Gates, Ballmer, Allen, Jobs, Bezos, Musk, etc., all fit into that category.

I'll close by apologizing to you.
