What most interested me was this quote about white children. "These children did not inherit college expectations. But they inherited job networks." I can verify this phenomenon using anecdotal evidence, where poor white children are expected to learn their parents' (generally their father's) crafts but not expected to learn anything beyond that.
While my own college-educated parents passed down their respect and appreciation for learning to me, I saw some of my childhood friends' parents pass down their mistrust and apathy towards learning to my friends. I was not surprised when I came back from college one spring break and learned that one of my old friends (white, poor, no college, terrible home life) was currently on the lam for killing a teenager over a drug deal. I was shocked by the fact that I wasn't at all surprised.
What bothers me more is how I can't relate to how hard life must be for this old friend, and especially how hard it is for primarily black children who inherit little but discrimination, through anything but anecdotes. I think this is more "friend guilt" than "white guilt." No one wants to see people they care for, or once cared for, victimized by systems beyond their control.
Therefore, based again on my own anecdotal evidence, I'm glad this study continues to receive attention.
