Just to paint you guys a picture.
According to some official researchs, an graduated american earns around $3500 per month. A brazilian in the same situation earns also around 3500, but in Real (BRL). So it's kinda 1 to 1 situation.
But, for example, a Logitech G27 costs 299 on the US, it costs at least 800 in Brazil. In other words, everything - specially tech goods - will be twice as expensive in this f&$#ed country filled with people who things it's all good.
Anyway, dispite that. Most brazilians manage to own those tech stuff. Just search about iPhone ownership here and you'll be sadly amazed.
