[flmqoovi] Pretty pop stars

Assume, non-controversially, that no one is born a good singer (a baby only knows how to cry).  Also assume, perhaps controversially, that everyone can become a pretty good singer: this follows from the Polgar Experiment.

Then, roughly, the people who become good singers are those with the best opportunities to do so, and in particular, a pretty performer gets hired more frequently.

This is different from the conventional criticism of someone succeeding as a pop star just by being pretty and not actually being skilled at their art.  In this model, the prettier person is objectively better at their art than someone who is not pretty, and has become so through more opportunities to perform or show, reinvesting income generated to practice and develop.
