I think the line "And I've never seen light but I sure have seen gold" is a reference to greed and how something like gold (that shines) can easily be confused (perhaps for someone willingly deceived) with light. In this case, the person has never seen genuine light but has instead seen a lot of this substitution that so induces people's greed.
What is also interesting is that gold is generally seen as rare (rarer than light) seems more abundant than light, thus implying how rare authentic light is that it should be rarer than gold.
