The federal government was commissioned to look at race agenda as we moved into the 21st century. The report was called the Hudson Report. What it talked about was how population is shifting globally, and specifically here in the United States. The workplace has changed a great deal in the past 20 years, with desegregation and women entering the workplace. The rules, policies and procedures that were used then, just don't fit today.
Education is the key for diversity to succeed.
The problem of working with other people is because upbringing and value systems are very different. This is why diversity training is needed in colleges. Let them be different, but harmonious, not trying to change their value system. Diversity is the blending together of many different cultures into a whole, but not like the traditional melting pot.
