(This program was originally broadcast live on December 10, 2019) The business of diversity is booming. Corporations and cultural institutions spend hundreds of millions of dollars every year on diversity training, yet despite the ubiquity and expense of these efforts, overall racial, gender and ethnic diversity remains an aspiration rather than a reality. Today on Midday: what's been tried, what has succeeded and what's flopped in efforts to achieve more inclusion in American life. Dr. Pamela Newkirk is a professor of journalism at New York University and author of "Diversity, Inc.: The Failed Promise of a Billion-Dollar Business." Dr. Newkirk joins Tom on the line from Argot Studios in New York City. (This program was previously recorded, so we can't take your comments or questions.)
