Yup, but money isn't great at motivating people to work hard; a lot of evidence implies it even does the opposite. And a huge chunk of that money is vacuumed up by administration.
Inner city school systems are great at grinding up passionate personnel, making them quit or just surrender to do things that look good on paper but don't improve anything.
Is it? How do you know? Have you reviewed the budgets? Do you work in education in Baltimore, and thus, have a sense of what an appropriate number would be?
I don't know the answers, but I do know this -- it's a hell of a lot less than what gets spent in the NY metro area.
According to the US Census[1], out of the largest 100 US Public School systems Baltimore ranked near the very top in spending per child (5th out of 100). Baltimore spent $15,793 per child. Only New York and Boston spent considerably more.
