Primary and secondary school education is similarly recession-proof. When a child turns five, he or she has to go to school, and needs to have a teacher. It’s a law; it has nothing to do with the economy. When property tax revenue drops, hiring slows down, but it can’t grind to a halt because the kids need teachers and there are regulations dictating how many students you can have in a classroom. Add on top of that, the fact that grade school teachers are heavily unionized, and you’ve got yourself a recession-proof industry.
