<p>If the cause of the education gap has political ramifications that people do not want to address, discourage or change, like single parenting, teenage parenthood or illegal immigration, then we must assume that those conditions will continue indefinitely and figure out how children from those circumstances can do better. It does not appear that we have the data to determine what exactly is the cause of the problem, and whether it is in fact, any of those 3 things, because we are not allowed to ask for the details of any given child’s circumstances. It is difficult to solve a problem when we don’t know the cause of the problem.</p>
