What happened to the middle class, blue collar man?

They're still out there. Most of non service blue collar work is being shifted to the south and it will continue to grow from there. For the time being union states are pretty screwed on that front.

Granted those working in the south aren't making quite what those in union states did 20 years ago, but their cost of living is much lower and their incomes are continuing to grow.
