Haven't you been listening? We're throwing money at Baltimore, 3x as much as in other jurisdictions in Maryland, and it continues to suck; yet the other jurisdictions--the less funded ones--are light years ahead! How much should the taxpayers throw at a school system like Baltimore? four times? Five?
I'm referring to the US overall, not just one particular jurisdiction. And wherever that money goes it doesn't end up in the paychecks of teachers, which is perhaps the best qualified ones are in offices and not classrooms.
