> If anything I'd expect the wage to have gone up

You'd think so, wouldn't you? The truth of the matter is most manufacturing companies are facing the same problem tech is right now: a "talent" shortage. The pay hasn't kept up with living costs in most areas. The days of buying a house and raising a family on an "industrial wage" are long gone. The pay is hardly enough to keep one person alive these days. As a result, nobody wants the jobs. The companies can't keep their assembly lines fully staffed, but they don't want to pay more either.
