Has MLK's dream been realized?

Over the years the income statistics of African Americans has increased. Although they are still not equal to whites. The total that Americans make (on average) each year is 45,000 dollars, although blacks (on average) make 30,000; whites (on average) make around 48,000. This inequality in income makes Martin Luther King's dream seem not to come true. He wanted everyone to be equal, as it says in the constitution, but if whites are making that much more, how are we all created equal? Whites on average make around 10,000 dollars more per year than African Americans. Martin Luther King would try to fight and make this the same, because it still shows that we live in a semi-racist society.
