"Gulf Coast job boom blooms in wake of Hurricane Katrina"

From this (also here):

The message is clear on storefront marquees, brightly colored banners and the handwritten signs merchants taped inside windows across this battered city: businesses reopening after Hurricane Katrina have a surplus of jobs and not enough workers to fill them...
Most of the people who've been able to return to New Orleans have been either wealthy or in the middle class, in part because their neighborhoods were damaged the least -- leaving a hole for business owners who depend on unskilled labor.
"The service industry and unskilled labor jobs are the ones really in demand and the people in that category have not come back," said John Trapani, a professor and vice dean at Tulane University's business school. "There will be a shortage of labor until population starts to return and who knows what percentage is going to return and when?"
The demand by service businesses for workers is set against a parallel demand for people to work in hurricane cleanup. Some employers have turned to immigrant workers from Central and South America to fill those jobs...

In 2TheAdvocate-speak, illegal aliens are "immigrant workers".
