This is an Excellent Question

Grant Wiggins:

The question I have is – why does SES predict achievement so well – not just at the extremes, but all along the graph? The older I get, the less sense it makes. And the more it is clear that a glib single-cause explanation of it is unacceptable.

Or, shouldn't there be a point of diminishing returns?
