What's dense about it?

If so much wealth is being created, why is everyone so poor?

It's both an illogical question and comes from a place of ignorance about a topic which one would expect folks nowadays to have some basic competence in.

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.
