The quality of happiness of an ordinary person, even an uneducated or lowly one, can be much richer than that of a wealthy or an intellectual person's as it's uniquely its own and can't be compared with that of another.  

Call this a gift or grace but of such I've no doubt at all as I've known such people.

We should never say someone is happier than we are-
what happiness we have, even a little, is itself adequate blessing.
