Its trying to promote self-improvement. Indeed for many of us, the "advice" in this vid is just common sense: E.g. - brush your teeth, read books, wear deodorant, own things instead of rent, take care of your kids.
But you'd be surprised (or maybe not) at how many of our black male youths don't really have a caring authority figure to teach them these life lessons. This video attempts to reach them at "their level". It does come off as a bit condescending and presumptuous, though. The rather generic name of "black people" is off-putting as well because the audience it is targeting is a specific type of black person - namely young black males growing up "urban ghetto" style without fathers, rules, or discipline.
