I would say a 40 year old Black person is more successful than a 30 year old Black person, which is more successful than a 20 year old Black person.

A 20 year old college graduate will have his options, but a high school drop-out will not.

Many of the Black men and women who attending high school and college during the civil rights era are now successful middle-class and upper-middle class.

So it is accurate to say that a 20-year old will be less successful than a 35 year old. If you want to analyze post-1970, you have to look at the generational gap and culture.
