Quotes: Reform "Probably Hurt The Very Poor"

I think education reform has probably hurt the very poor... because the better-off portion of low-income kids are more likely to find alternatives [like charter schools]. That leaves the original schools more concentrated in their disadvantage, and thus even worse learning environments. - Author and NYT Sunday Magazine contributor Paul Tough

A popular thought but what is the evidence for such a claim? In my experience, I've not found it to be the case in districts like Denver where the poorest and worst schools are better. Is this true for NYC? how do you know?
