When Martin Luther King had his dream, the majority of White American hates Black. So when I see America today, I think that his dream his achieved and the first part of this article confirm my opinion
In fact in many states and also in states with predominantly white people, governors are today African-American. At time of Martin Luther King, this was not thinkable.
Moreover The future president can be an African-American president.
In fact, Barack Obama is one of the three candidates who HAS today a luck to be in the  
White House in 2010 and he haven't less luck than one of other concurrent to win this presidential.
Even if today there is again many violence and racism in the USA and even if the majority of post graduate are white (as shows the continuation of the text) I think however that his dream is almost achieved.
In fact, we aren’t in a perfect world, and total peace and prosperity isn’t possible and to my mind, the racism situation of America will be finished with passage of generation, as religion who dispear from a generation to the other one. But for this, we must let time act.
