The problem is that progressives operate as though the state owned children as joint property. Dana Goldstein, writing in Slate, urged her fellow progressives to resist the temptation to homeschool, arguing that the practice is “fundamentally illiberal” and asking incredulously: “Could such a go-it-alone ideology ever be truly progressive?” She went on to argue that the children of high-achieving parents amount to public goods because of peer effects — poor students do better when mixed with better-off peers — meaning that “when college-educated parents pull their kids out of public schools, whether for private school or homeschooling, they make it harder for less-advantaged children to thrive.” She does not extend that analysis to its logical conclusion: that conscientious, educated liberals should enroll their children in the very worst public schools they can find in order to maximize the public good.
Excellent point. And following up on that, Liberals who profess this belief should also live and work in poor neighborhoods.
I'm not going to hold my breath.
