How can we morally address racial inequality?

We learned that there exists a [url=http://www.usatoday.com/story/money/personalfinance/2013/02/27/racial-wealth-gap-growing/1948899/racial wealth gap[/url] in America rooted in our explicitly racist past. How can we address this gap in a morally fair way? (Some would say that affirmative action is one way that we can morally address this gap, for instance. If you think affirmative action is wrong, you should not only say why, but discuss what could be a moral alternative.)
