NBC: "In New Orleans, the working class disappears"

Carl Quintanilla offers this short article on New Orleans' working class not coming back:

Despite the mayor's attempts to bring them home, New Orleans has become a closely-watched experiment in what happens when an entire income bracket disappears.
"If they can't bring back these people, you're going to see the city's infrastructure fall apart," says Dr. Robert Blendon of the Harvard University School of Public Health.
Some residents can't return because their neighborhoods, often poor, are still deserted and have no water or power.

Some - we aren't given even a guess as to how many - have found better opportunities elsewhere. Then, the NBC reporter makes another leap:

There are some workers who've moved in to satisfy demand. They're mostly Hispanic, raising a controversy on its own. Some of them line up to do the most menial of jobs, like clean up, and signs offer them $10 dollars an hour.

Is "Hispanic" the best description for these workers? How about "illegal aliens from Mexico"? Wouldn't that be a more truth-based description? Of course, if Quintanilla wants to make "Hispanic" equivalent to "illegal aliens from Mexico" he should say that. Alternatively, he should tell the truth.
