Unless I missed it, your quote only mentions the comparative wealth of modern robber barons to their predecessors, and not the comparative poverty faced by the world today. So when you said, as I understood it, maybe today’s robber barons aren’t any wealthier than their predecessors but that the rest of the world is poorer (comparatively speaking) than in previous times, I said I believe that the rest of the world has gotten poorer than it has been before due to what I perceive as current robber barons working to hoarding away resources from the rest of the world’s current availability. I hope this makes sense.
