Jonathan Kozol, in his Letters to a Young Teacher, makes this comment in his discussion of vouchers:
"If education is perceived not as a universal good but as a personal commodity, and nothing more, to be consumed for personal advantage only—if this is all it is—then it's very hard to argue with a parent who sincerely thinks she's being double-billed" (p. 145, pb edition).
Then, what is education? "[A] personal commodity"? Or "a universal good"?
