America's racial structure was never ideal from the start.
Blacks were brought as slaves to toil on the cotton farms for southern elites. In smaller numbers, Asians came working under slave-like conditions for other elites in charge. Both faced discrimination that tried to lower their opportunities in order to enforce their lower position in society.
However, you would now notice that Asians are unlike any other minority. They carry more power and wealth than whiites - speaking on averages. Blacks on the other hand remain in dysfunctional communities and are still present in a lower socio-economic status.
Now while there could be multiple reasons to this, let's first consider the approach for equality. Blacks largely followed liberal leaders such as Web DuBois, placing a focus on protest for equal treatment. Asians largely took an approach more similar to Booker T Washington's ideals. They focused on education and economic opportunities to readily exploit.
As a result, who do you believe is in a better condition nowadays?
Asians remain segregated at times, for you can spot multiple "Chinatowns." However, you'd also find Asians who are much more integrated - almost entirely. Nobody really minds either.
Blacks are pseudo-segregated. They have been forced to be desegregated with mixed results. Many of those who co-exist with whites will still form some level of self segregation, which are in dysfunctional communities promoting cancer such as "thug life" or single motherhood. Those who attempt to better themselves may be branded as "Uncle Toms, Oreos, Whitewahsed," or other such derogatory terms.
Can we conclude from this that blacks have followed the wrong method for civil rights, and due so today? Their modern condition is not due to "Institutional racism" (given affirmative action and reverse discrimination policies) but poor communities, crime, cultural marxism, and a failure of working to a sense of upliftment.
