This distinction isn't simply rhetorical. If there are cultural forces at play, one of those three things must be true. What's more, the political implications of each are different. If the black culture explanation is correct, it suggests that admonishments against the behavior of black Americans — the sort of thing that Coates has consistently objected to — are a proper response to entrenched poverty. If there's a culture of poverty, there needs to be a broader cultural realignment among all poor people, one that's not limited to the black community. If there are no internal cultural forces at play, then the "racism exists" explanation becomes more significant.
Put more simply, there are three options for why black people continue to experience higher levels of poverty: it's in part black people's fault, it's in part poor people's fault, and it's society's fault. The best answer, without question, is the latter.
The culture-of-poverty option
Let's say, for the sake of argument, that the problem lies with the second option, that there is something about being poor that results in future generations being poor.
If this culture exists, what are its components? Ryan's remarks offer one view: it involves "men not working and just generations of men not even thinking about working or learning the value and the culture of work, and so there is a real culture problem here that has to be dealt with." Or, put more crassly, parents who have been out of work take refuge in the welfare state, living on food stamps and government services, and their children learn that this is a viable means of survival.
Last November, the National Bureau of Economic Research published a study suggesting that the children of people who receive government benefits are more likely themselves to receive such benefits. "[W]hen a parent is allowed [benefits], their adult child's participation over the next five years increases by 6 percentage points," its summary reads. "This effect grows over time, rising to 12 percentage points after ten years." (The conservative National Review embraced the argument, unsurprisingly.)
The study — conducted by looking at Norwegian, not American, benefits usage — found a relationship. But the noticeable uptick in the likelihood of children signing up for benefits programs was to the effect of being 1-in-16 or 1-in-8 more likely to do so. That's hardly a suggestion there is necessarily or even probably a transfer of the inclination to avoid work over generations.
There simply isn't a strong argument to be made that identifies attributes of enduring poverty from attributes common to the black community. Chait never presents one clearly.
In fact, in his most recent response to Chait, Coates argues that his opponent confuses the first and second options, conflating black culture with the culture of poverty. Here is what Chait wrote, in the closest approximation of a definition of that culture, and citing a paper linked in this essay by Jamelle Bouie.
[The paper] surveys some of the best research evidence of the detrimental cultural outgrowths of concentrated urban poverty on parental expectations, sexual behavior, the willingness of students to engage in beneficial activities, and other things. Culture is hard, though not impossible, to quantify, which does not mean it doesn’t exist.
Coates' point, in part, is that Chait is pointing to things that are primarily specific to communities of color as being representative of the culture of poverty at large. But, further, that blurring that line tends to happen more when the "roots of poverty" being identified are more rampant in the black community.
This elision is not particular to Chait. In the 1960s, when 20 percent of black children were found to be born out of wedlock, progressives went to war over the "tangle of pathologies" choking black America. Today, 30 percent of white children are being born out of wedlock. The reaction to this shift has been considerably more muted. This makes sense if you believe that pathology is something reserved for black people.
The black culture option
Perhaps another assumption is in order. Let's assume instead that the black culture option is the correct explanation. That pathology actually is something reserved for black people.
