Katrina only affected a relatively small area: a small portion of the Gulf coast. So of course help poured in. It's not like the entire US was hit by a Category 5 hurricane!
An economic disaster is different: it hits the whole country at once, and then other parts of the world because of trade disruption and other economic ties. There aren't going to be any places left to "pour in" help; they're all going to be suffering.
