Better indicator?

[jsburbidge]

This Geoffrey Simpson article notes that a family possessing a dictionary (or not) is a better indicator of whether children will go to University than income level.  Wouldn't possessing a copy of Fowler be a better indicator still?

(Disclaimer: I have both The King's English and (the second edition of) Modern English Usage, as well as the original Fowler-edited Concise Oxford Dictionary.)
