Race, illegitimacy and education

Hispanics have a 53% illegitimacy rate, African-Americans a 73% rate and among the white poor and working class, the illegitimacy rate is now 40%. Blacks and Hispanics have high school dropout rates of up to 50% in many cities, and many who do graduate have math, reading and science scores at seventh-, eighth- and ninth-grade levels. Can the United States really survive as a major economic power when whites are being replaced by blacks and Hispanics?
