I heard it suggested recently that the word "fair" actually means "getting what you deserve" instead of "everybody gets the same thing".  The latter lines up better with the idea of "equality".  The topic was brought up by a high school teacher who's sick of students claiming something's not fair (e.g. one student getting punished for something while another student isn't).  She says to them, "Based on your performance up to this point, this is the outcome you deserve.  That's only fair." #psychology
