Unemployment rate hits five-month high
For the last 12 months, wages have gone up 3.8 percent. But those wage gains are still trailing inflation, economists said.

Of course, many are still saying everything is really fine.
What I have not seen is what the unemployment rate would be if so we didn't have a bunch of reservists and national guards in Iraq. Of course, w/o the war in Iraq, there would be less government spending, so that would also affect the economy.
