Brasil facts of the day

I saw this article over at Marginal Revolution and am amazed that the "middle-class" salary in Brasil is $635 a month. With the crappy dollar, that's approximately R$1050 per month. I currently fall into that category, but I don't have to pay rent or buy my gas or pay for car repairs. Thinking of it like that makes me wonder how Brasilians are making ends meet at all around here.
We work with the lower class and the poor of the poor, and I know that I have never known what it is to want for anything.
