Primary to tertiary? Does that mean it includes what college students through grad school spend themselves? Because that would shift perception of this a lot.

Edit: The original data does include public funding and private funding:

Every year, governments, private companies, students and their families make decisions about the financial resources invested in education.

They do break it out, but I can't tell if the graphic is using the total or just the public funding.

So this graphic might just be: Americans spend a stupid amount on college.
