The Katrina "victims" were the kind of people who live by different rules than mainstream society... the kind of people used to collect government hand outs and hang out all day in the 'hood, the kind of people who bitch about illegal aliens rebuilding New Orleans but refuse to get their hands dirty.
Yet we're told that those middle-class "bourgeois" values are a bad thing, that they exist to disenfranchise the proletariat and to perpetuate a stagnant status quo. On the other hand, the reprehensible conduct of the scammers and frauds is earthy, rebellious, exciting.
In the Marxist world, good literally is bad, and vice is a virtue.
