Despite the passage of the 1964 Civil Rights Act, which prohibited discrimination in employment based on race, sex, religion, and national origin, African Americans were continuously relegated to low-paying, unskilled jobs. Many industries refused to train or promote African Americans, only permitting white employees to compete for supervisory positions.
Looking at most high level jobs in many industries, we continue to view a sea of white male faces – now sprinkled here and there with women and people of color. This is not a simple accident, but a product of decades of purposeful exclusion. I suspect we will need to put as much effort into creating diversity as our society used to employ in actively suppressing diversity to get real racial and gender diversity in business and politics.
