I listened to clips from Martin Luther King's “I Have a Dream” speech with African-American Cultural Society President Joseph Matthews for the Jan. 15 edition of “Free for All Friday,” on WNZF. Here are three things I learned. First, despite many social advances, one statistic provides alarming evidence that there is a great deal more progress needed to give future generations greater opportunity: "In 1968, unmarried women were the main breadwinners for 20% of [black] households," University of Florida professor Sharon Austin reported. "In recent years, the percentage has risen as high as 72%." King said, in his immortal speech in 1963, that the freedom of whites is "inextricably bound" to the freedom of blacks. I believe that the same can be said about the health of our communities: If black families are in poverty, we are an impoverished community.
