Hidden behind the charitable veneer is the real purpose -- establishing the pattern of public funding (after being washed through the hands of the so-called donors) going into private school bank accounts.
It would be hard to overstate how incorrect that sentence is. There is no "public funding" involved. Referring to donors as "so-called donors" is nonsensical. And one cannot "establish" a pattern that is already firmly established. I realize the World is more devoted to left-wing ideology than to actual children, but they're going to have to do better than this.
It's a good thing for Lexie that the World's editorial writers aren't in charge of Arizona's government.
