This is a thought provoking point. We frequently point to the exportation of jobs which is a factor, but something that is rarely discussed and is also a huge factor is the extreme productivity increases we have seen over the last decade which have literally eliminated a lot of skilled or semi skilled jobs. Yes productivity increases are good, and have led to record corporate profits at many companies and helped fuel the bull market but the side effect is a lot of folks left without jobs.
I worked in an auto plant one summer back in the late 60s. The assembly line shift had at least a couple hundred workers, fitting the cars with every part and piece. Last year I toured the local Volkswagon plant and I was astounded at the fact that it was almost a ghost town. There were a few people walking around with notebooks and some monitoring computer displays and talking on the phone but that was it, all the work was being done by robots.
When's the last time you talked to a bank teller? ATMS have replaced most of that. Check out lines in grocery stores and big box retailers now have self-serve lines - more jobs eliminated. Computers don't just answer calls, they route calls, provide information, schedule service appointments and even initiate calls to you.
The bottom line is we can do everything we could do 10-20 years ago with half the people or less, so like Bill points out, what is left for people without professional degrees except the service jobs? No that doesn't justify paying $15/hour for flipping burgers, but it does have to change the way we look at the min wage. I would like it to at least be brought up to historical levels of around $10.50/hr and then indexed to inflation. Also as pointed out when the min wage is increases it pushes up other pay scales across the board.
With the enormous gap between middle class and lower wages and upper 5-10% wealth growth which has been disproportionate, we do need to take measures to level the playing field a little bit.
The Chipmunk has offered an idea - it involves giving corporations tax breaks for having a profit sharing program for employees. I think the idea might have some merit.
