Does economics or political theory focus on centralization, practically speaking? Not as a normative claim. What the actual effects are like. It just feels like we're at a centralization of power of unprecedented scale, to the point where no previous theories or models could really apply (in order to make analytical progress - I mean sure feudalism is honestly becoming a scarier and scarier analogy but still, there are significant differences)

I'm pretty much only thinking about these kinds of problems at my job at this point, so this is important to me in that regard
