BS!

Did you do a proper research?  How many couple did you study (the sample size you used to draw your conclusion)?  What is your social status?  What are those couples' social status?  Where do they live?

I live in a metropolitan area and in upper midddle class.  I personally know TONS of people in uppper middle class and upper class who enage in interracial marriage and  have a happy marriage.  Indeed, almost all interracial couples I know are wealthy and very well educated.
