What is the author trying to say? The truth is blacks and Latinos need to step it up.
I come from a Mexican-American family, and have ten aunts and uncles. I'm constantly amazed (or is it baffled) with the disparity between each of the grandchildren, even within the same family.
My aunts and uncles all have at least 3, and at most 5 children. Some ended up in prison, some ended up pregnant at the age of 14, some dropped out of high school and some went on to finish college. Most are employed at various levels. But when it comes to which ones are 'successful' and don't have the problems the others have, it basically came down to personal choices they made along the way, and continue to make (the oldest is 42 years old, the youngest are just now finishing high school).
The worst-off grandchildren generally have parents in equally bad situations. But one family has two convicts, a do-nothing, but then a nurse and a teacher. The biggest 'help' seems to be from the parent marrying someone who's from a better situation, but it's not always the case. Only about 5 of the grandchildren are married.
My point is these kids all came from the same schools, same neighborhoods, same families, and some of them managed to make it through while the rest became statistics. Much of the problem is that the majority have all stayed put in this rust-belt city with no jobs and no future.
