Except that it's very consistent that the states with strong unions have the highest academic achievement and the states with weak or no unions have the lowest. So the facts easily refute this common but erroneous opinion. (This is most likely because nonunion states correlate with high poverty, and so does low academic achievement, but it conclusively disproves the notion that unions are to blame for low academic achievement.) (Also, whoever told you that lied, so disbelieve anything else that source told you -- fool me twice shame on me.)
