I think they’re saying that an increase in school funding doesn’t necessarily lead to an increase or decrease in quality of education. Like maybe it’s essentially uncorrelated above a minimum amount to fund basics (lights, desks, teachers, etc.). There’s a lot more factors than money at play here. In other words, a poorly-run school with bad policies, teachers, etc. is crap whether it has X million dollars or 2X million, and a well-run school is good even with a small budget.
It’s just a rainbow, Michael. What could it cost, ten dollars?
