I don't understand the concept of 'mediocrity' nobody is mediocre. some are more adept at things than others that is not a gauge of worthyness as a person.
Of course those who are suited or educated enough get roles requiring specific attributes, that's not to say there aren't roles out there for those with non specific talents.

Nobody need feel entitled or undervalued, should you excel great if that isn't possible that is also great.
