At the end of benching we say Na’ar Hoyisi (I was a child, now I’m old, and never saw a righteous person...need to ask for bread) Please elaborate, because that is patently not true

This is a bothersome verse and several suggestions have been offered. My favorite is the explanation of Midrash VaYikrah Raba: I never saw a tzaddik who was "ne'ezov" thet is divested of his yira'at shamayim (fear of heaven) when he was so destitute that his children had to beg for bread. The verse is a comment about the faith of the tzaddik, not about the way G-d runs the world.
