The problem with these sorts of averages is that it doesn't paint an accurate picture. There are schools with buildings in disrepair and schools without the same resources as other schools. And some have waaay more resources and spending per student than most schools. This is, in part, because a lot of states don't fund their schools by redistributing money across all schools. Instead, they rely on the school district's tax base - which means if you are in a poor neighborhood, you probably won't have as much funding. The same goes for being in an area that doesn't utilize the public schools as much as other areas (using private schools) - this decreases federal funding that is reliant on the number of children going to your school.

All this means that it isn't really evident that money doesn't translate into better results. It isn't strictly funding, that is true - poverty seriously affects how well students can perform, for example - but it should be quite obvious that a school that cannot afford maintenance, proper computers for students to learn on, or enough staff so that classes are a manageable size can't really teach as well as a moderately funded school.

This is false. State and federal funding makes up the discrepancy between more well funded and less well funded school districts in nearly every state. There is obviously differences between states, but states have vastly different costs of living. But even then: Mississippi spends as much on education as France. Overall, the US spends more not just in dollar terms, but as a percentage of GDP than most big European countries: https://cdn.statcdn.com/Infographic/images/normal/15434.jpeg

Some of the worst cities have the beat funded schools. Minneapolis spends as much per student as Switzerland. Baltimore spends more, and spends as much of more than the rich suburban schools around it. The US also has relatively low rates or private K-12 compared to the Scandinavian countries, the Netherlands, Belgium, etc.
