Why are meaning and caring synonymous in most peoples mind?
By 'meaning', do you refer to 'meaningful life' (pervasive feeling of satisfaction), or semiotic reference? And by 'caring', do you refer to 'compassion for others', 'involvement' or 'motivational relevance'?
Well, to be precise, they relate to negation of meaning with the negation of caring. I think caring for the purpose of this discussion any of the three will work for the moment at least. With respect to meaning, I'm definitely not referring to meaningful life, more the semiotic sense.
