I think this particular song is talking about a pervasive problem in our modern society, which is that you can know a lot of people, but still find something missing. It does offer some hope, with the line to "not give up, util you drink from the silver cup, which I interpet to mean never give up until the time of your closing of this life to the next-where one will experiece a banquet with silver cups in Heaven and never again feel like a pariah. I think the other line refering to the next life is of course-ride the Highway in the sky.
