Do you have some links and maybe some elaboration on the point you're trying to make? From my short reading, it sounds like the narrative is that the disaster gave both sides the political cover they needed to make the concessions they've long known they needed, and allowed effective reform to happen. Is that what you're suggesting?

It's interesting their article doesn't include the normal dispute of the post-Katrina improvements, the fact that the cohort of students is very different.
