Muddle class

Here's the latest installment in the long-running soap opera that is Brazil's "emerging middle class". It's in Portuguese but to save you the bother of looking I can sum it up as follows: confused journalist writes confusing article based on recent research into how confused Brazilians see their own social standing, eg AB, C or D class. Seems no-one has a clue what they are. All we can say, as before, is that ex-President Lula's definition of middle class - anyone earning 2200 reais a month - was and is absurdly optimistic.
