The widespread reports of Katrina "refugees" actively engaging in criminal activity and mooching endlessly off various public and private social service agencies. Not that the folks in this story sound like perfect angels, but they sound like they don't have an attitude problem, and are trying as best they know how. That's a lot better than many.
I realize there were some perfectly civilized, self-supporting people displaced by Katrina, but the vast majority of those either lived in areas that weren't completely devastated and have gone back, or relocated to other places where they had strong family or other ties that enabled them to resume fully functional lives fairly quickly. They aren't the "scattered" that I was really referring to. I was referring to those who either left on their own or in the huge bus convoys, with nowhere in particular to go and no plans. That very large group seems to consist mainly of people whose lives were a complete mess before Katrina, and who have made little serious effort to embark on a different lifestyle since them.
I guess what gives me positive vibes about the featured family is their readiness to say that Katrina was a good thing that happened to them, despite the fact that they are still far from achieving their goal of a settled stable life. They seem to be admitting that they needed a good swift kick in the pants, and I haven't heard much of that from the Katrina refugees, despite the fact that it's clearly true for a lot of them.
I interpreted your "scattered" to refer to everyone who has relocated due to Katrina (which includes me). I was going to tell you that the majority of people who've had their lives dramatically changed due to the storm are hard working people who are living their lives in such a way as to not be in the news. :-)
