Let \( n \) be a fixed positive integer. Let \( S \) be any finite collection of at least \( n \) positive reals (not necessarily all distinct). Let \( f(S) = \left( \sum_{a \in S} a \right)^n \), and let \( g(S) \) be the sum of all \( n \)-fold products of the elements of \( S \) (in other words, the \( n \)-th symmetric function). Find \( \sup_S \frac{g(S)}{f(S)} \).
