Fast food chains have high turnover. People are always leaving, so even if McDonalds was slowly contracting, they'd be hiring new people at a high rate.
This press release does create a sense of optimism about the economy which might be justified. The economy looks pretty good from my position, but could look pretty lousy to somebody who's unemployed.
My feeling is that people have been getting pessimistic because of $4 gas and the talk about the federal deficit. I see a lot of evidence that companies of various sorts are moving forward with initiatives all over the place so I'm a believer in the recovery.
