First, the illogical part: the statement was about "inequality" to which you asked about wealth generation. These are two separate issues, and inequality is not, logically, necessarily tied to wealth generation. So "How does creating wealth hurt others?" is, at best, a non sequitur.
The ignorance part: there is a lot of empirical research over many decades showing the negative impact of wealth inequality on societies. With Google and AI there's really no good reason to ask such ignorant questions when in a moment you could educate yourself, and then ask an informed and thoughtful question instead.
Perfectly reasonable to debate if there is too much wealth inequality but just hand waving at its mere existence doesn’t add anything to the discussion. The person you’re replying to was calling this out. Ironically, you’re trying to shut down the discussion in the name of perpetuating it.
Maybe you’d like to explain how you think about wealth inequality, since you say you’re interested in a more freely flowing discussion. I’m all ears.
Still, I can rephrase my contention: In a basically capitalist society, growing societal aggregate wealth necessarily grows inequality. Even a Nordic welfare state, which many (including me) hold up as a robust way to promote income equality, is going to show more variance in the size of pie pieces as the size of the pie grows (even when you account for taxes).
