as someone who grew up attending a majority black school district, this is not really true.... underfunded majority minority districts typically more than have the gap made up by federal funds and the causal evidence on returns on education funding suggests extremely limited impact if any
That's just false. Nearly every state relies disproportionately on local property taxes to fund schools. Federal dollars tend to be supplemental and come in the form of food subsidies or Title grants. They absolutely do not "more than have the gap made up" unless you're in a state with an equity funding pool (like Washington).
I have heard that Baltimore school performance is the counterpoint here, but I have never dug into it myself. Do you happen to know if there is a material point there or obfuscation of some form?
Title 1 schools can get a ton of money. Smartboards in every class, school supplies fully stocked, not the usual "grim downward spiral" feel of a public school.
