Globalization Dynamites The Middle Class

I wonder which American middle class these 'grow ourselves out of debt' types are looking at? The road to the middle class that used to go through the manufacturing sector has been dynamited by globalization. There's about one lane still open, and not many unions still able to fight for a good wage. If this growth is expected to come from service/re­tail/paper pushing, I don't see it. The middle class independent farmer is also on the ropes.
