I think that depends on your definition of rich and poor. Did he have material possesions-No. He spent his life ministering to others and my verse for that is-the New Testament!!!However I do feel that he was rich in His spiritual life he was God and would speak to God the Father and had a closer relationship with him than we can even imagine.I think anyone could read through and see he didn't live in a mansion he was a carpenter(laborer) but he had a greater understanding of God's plan for the world and how he would save us all from sin. So I think the answer to your question is both.
