On the subject of school vouchers — or more broadly, the public/private divide:
We’re dealing with people for whom, unlike most other words — grapefruit, mountain, Tuesday — there is no entity to which the locution ‘public’ corresponds. It is, like ‘thnork’ or ‘promble’, something you can utter, but which does not signify anything. [From School vouchers fail another accountability test – The Carpetbagger Report]
As with any other conservatarian scheme, the goal is to privatize the benefits — the higher-performing students and the money their parents can afford to pay — and keep the risks — kids from low-income families, with the attendant poor nutrition/health issues, as well as kids with learning disabilities or special needs — in the public sector. Equality for me but not for thee . . . .
