I said it’s an averaging factor not an absolute match.

A senior with a LLM will likely still outperform a junior. A CS major with an LLM will out perform an English major.

But is the senior out performing the junior at a level that warrants the difference in salary?

Then people will point to the intangibles of experience, but will forget the intangibles of being fresh and new with regards to being malleable and gung-ho.
