I think the question we need to ask is WHAT teaching assignment drew only $7,500? Could that have been a driving instructor for summertime driver ed? That's pretty common now having been driven out of the regular school year by nanny-nots who fail to understand that driver's ed is as American as apple pie and failing algebra for the third time eh!
Federal minimum wage for the year reported was $7.25. Now I suppose it's not too hard to imagine the way bloated administration trying to pay someone tip wages but I doubt it.
