Is it possible to be poor but happy in North America?

I went to a rich university and my child hood friends were rich so I do not know what it's like to be poor and I'm not sure I ever had a friend who was poor. I ran into a guy who bought pizza from Pizza Hut one day and a few months or years later I saw him working as a janitor at the university. He had a smile and looked young and was on the phone with a good friend and laughing when he went to get the pizza so he might have been poor and happy but they make $30.00 an hour. They are not that poor.
