I don't think we can direct a whole group of people, based on skin color, to seek certain types of work. I think we need to examine what prompts a person to seek a particular career. Perhaps we might find that society (parents, educators, the media) do not shine a bright enough light on those who succeed in non-glamorous jobs. There are role models out there, and we should be helping kids of all races to see what these role models have achieved, and to formulate in their minds a healthy definition of success.
Someone on this thread mentioned Thomas Sowell. His book, A Personal Oddysey, should be required reading for all high scholl freshmen. It is inspirational to see what an intelligent, determined person can achieve against the odds.
However, we need other role models as well, for students who do not have the intellect or drive of a Thomas Sowell. Students need to hear about people who have succeeded in other walks of life, and to understand what they had to go through on the way to success.
