I wasn't talking about US, and that's exactly the point: global poorest are rapidly improving. And the only reason why a national economy like US is seeing income inequality is exactly because in reality, it's not a "national economy". It's part of the global economy, and in particular it's the part where the richest people from all around the globe end up.
