Assuming we're talking about socioeconomic status...that's a tall order.
In the long term, black culture will just have to change. It's way too anti-intellectual. Way too many kids wanting to be rappers/athletes, not enough wanting to be engineers. Another important thing would be building up solid social networks - I noticed coming out of college that a lot of white people had family members and friends hooking them up with jobs, which is an advantage most black people don't have.
Passing down wealth is also important. It's been observed that white families tend to pass down wealth, while it flows in the opposite direction in black families. For example white people are far more likely than blacks to get inheritances, money for a down payment on their first home, trust funds, help paying for college, etc. from their parents/family. So wealth is passed down in that way. On the other hand, when your average black person gets a good job, they'll have to spend a lot of their money supporting parents/relatives (I can attest to this personally) and thus have less chance to accumulate wealth or buy a home. Hard to do much about it on an individual level but it's definitely a factor.
