That's an interesting perspective because Delaware and Alabama have the same percentage of fatherless children. West Virginia and Rhode Island are almost the same as Alabama. Yet they don't have the same problems as Alabama.
Perhaps you're missing the core problem? Which is that Southern states made a concerted effort following the Civil War and again following the Civil Rights Era to assert their independence from the federal government by not providing services to their residents, especially in public schools. Over time, it has hollowed out those states' ability to prepare their entire population to be competitive on the economic stage.
It shouldn't be surprising that many southern states are in the bottom quintile when it comes to early education.
For comparison sake, both Rhode Island and Delaware are in the top quintile for early education (yet the same rate of fatherless children) while West Virginia is right there with Alabama.
So what you're seeing down there is that what was originally a method of defying the federal government has led to long term intellectual and economic impoverishment of the entire state that hurts everyone who lives there.
