Have AA laws not worked?

The point of Affirmative Action is to correct past injustices for being discriminated against in the past. This discrimination could be in the education field or in hiring practices. Now the Affirmative actions laws starting coming into play really in the 1950's with Brown v. The Board of Education. Similarly, in 1961, Affirmative Action laws were really enacted with the Executive order from JFK. So my question is this, Have the injustices not been corrected now? The generation that is entering formal education as well as the work force has now had the same opportunities as everyone else. Odds are, most of their parents were protected under these laws that really came into play over the last half decade. Does this mean that the laws now are not working as planned? Even though they were put into action and saying that people are to get equal opportunity does this mean that things haven't been evened out yet? Another question I have to ask is then those that claim that they have not had equal opportunity and their parents haven't had equal opportunity, is it because they have not taken advantage of the edge they have had over the last 50 years? Please feel free to comment below I am genuinely curious to gage a response.
