“But IMHO we shouldn't go around simplistically implying that all social ills will be solved by neutering the billionaire class.”

You’re right. Instead of implying, we should be taking active steps to do it.

Right, giving up is actually how these things end up becoming principles/laws. Power centralizes because people become complacent and ignorant on matters of power, so there ends up being a power vacuum, to which others seize the opportunity. But absolute power centralization almost never occurs, due to the delegation that is necessary to wield that power in practice, and so these two forces end up balancing each other. As such, the equilibrium point (or point of maximum entropy) ends up being some type of oligarchy. But anyone can take steps to address this and adjust this equilibrium point, but it takes active work.
