If you agree agree with the GP that people should be paid based on their negotiating skills, then you also support paying people regardless of their performance. Those are two mutually exclusive criteria.
We're not discussing a binary, though. Negotiating skills can't completely untether compensation from qualification/performance, but they absolutely loosen the two. If I am a junior employee who is skilled at negotiating comparing my salary with a senior employee who is not, the delta will be far smaller than if our qualifications were the same but our negotiating skills were reversed.
People who were given "You're #1" ribbons and awards for participating regardless of their performance.
