Hmm, yeah I don't know how the information was compiled. I would take that infographic with a grain of salt to be sure. It was created using data from 2009 and who knows how many hands it passed through before becoming an image. Still, I thought it was a nice, general illustration.

As far as variance in pay, I have no idea. What you say makes a certain amount of sense as conjecture, if only because most developed nations have a lower population and smaller geographic area than the U.S. I don't know for sure who is a teacher on hubski, but I know there are a few. Maybe we can ask them?

I know that in the Northeast, teachers can definitely make a good wage, depending on district and whether or not they belong to the teacher's union. I know a woman who graduated a year ahead of me who was able to buy a lake house on Winnipesauke only a few years after she started working as a teacher because she got into the Boston teacher's union right away.

Maybe it's just because I'm from snooty, old New England, but I'm not surprised to hear someone say that about the South. My only experience with the school systems in the South is from things my relatives in Florida have complained about. Is Florida considered a part of the South?
