Do you mind citing the source of that information? Because I have a lot of sources that cite economics and structural inequality (job restructuring, spatial mismatch, high unemployment rates, and etc) as the cause for the decline in black marriage rates and rise in out of wedlock births following the Civil Rights movement (specifically in the black community).
The Truly Disadvantaged is one. In fact, this book, using a landmark Harvard University study, completely dismisses the relationship between welfare and out of wedlock births. I can provide more sources if you want them. I would be interested in reading your sources so I can compare the studies and come to a more informed conclusion.
Here is a link to a summary of the book:

I look forward to reading your sources when you shoot them my way
