I understand what you are saying, but really don't think that suspicious causality is what the article is about at all. It's about selection bias. (not the same as causality)
Indeed after reading the article I feel it is generally well written and compelling. However the contrived teacher union scenario is a big distraction for me as I was reading the article hoping that issue would be addressed and it wasn't. It would have been much stronger without this gaping logic hole introduced in the beginning.
