Also note the sharp drop in the stock market along with a sharp rise in unemployment that coincides with 9/11/2001. Although the small size of the charts makes it hard to show exact dates, memory recalls what a profound change 9/11 brought about in the spending and investment habits of people. It should be pretty obvious that 9/11 wasn't the fault of the present administration.
BTW, the first chart is more than a little deceptive in its design.
Anyway, with all that said, we still need to look at this issue. Our manufacturing has taken a downturn in the last couple of years and America must face up to the fact that we are pricing ourselves out of the business. But I will contend (IMHO) that it isn't wages that are the primary culprit, but over-regulation, excessive tort, and unfunded governmental mandates that are choking our business environment.
Dubya needs to do what Reagan started to do - Get the government off the backs of the people!
