Yes. Jim Brown.
Jim was a football player, an actor, and an angry black man of the 60s.
While angry, he always advocated self reliance and getting out of poverty by starting your own business in your own neighborhood and hiring black people from that neighborhood to work for you.
When Brown could have sat back and enjoyed his money he chose to become involved as an advocate for equal rights and self-reliance. Yup. He looked kind of dumb in a dashiki and he still wears the silly hat.
And one day, I swear he's finally going to make it onto that truck in "The Dirty Dozen."
