Of a vast Chicago Tribune/Asshole Boss syndicate that doesn't want you to Know the Truth about the manufacturing labor market.
Well OK then.
First, all kinds of factors go into local labor rates as well as the vitality of the local economy as a whole. And second, imputing to an entire economic sector the experience of one anecdote or one company (however true that one example many be) is a mug's game, whether that company is run by an angel who will pick up the tab for sending her people to college (I know several such) or a vulture who will churn and burn his people without mercy to make an extra nickle (I have run across plenty of them too.)
Instead, here is a link to the Bureau of Labor Statistics. Your tax dollars at work!
I haven't seen the BLS at any of our recent Chicago Tribune/Asshole Boss syndicate luncheons, so have a look for yourself and decide for yourself.
