It's hardly as simple as that. The cycle of poverty is not simply a practical one, it's also a socio-cultural one; hence why tools like Affirmative Action exist in order to make mobility more commonplace for minorities and hopefully wean them off anti-intellectualism and "selling out and becoming an oreo".
I already admitted black people are more statistically likely to commit crimes; but, given the percentage of blacks who live in poor socioeconomic conditions compared to the percentage of whites, of course they are going to be more likely. It does -not- imply any inherent defect in the race itself.
