Note that usually there is an option to compete geared I.e. With a shirt or squat suit, or you can compete raw. Geared lifters compete against each other and raw lifters with each other. But as I mentioned earlier: "If you can't lift it raw, you can't lift it".
Yeah, but when you see those kids lifting, you're thinking "do you really need a shirt to lift something that light?"
