Even with favorable exchange rates, living in most metropolitan areas in Brazil is very expensive and you are likely to earn more working for Brazilian clients - right now unemployment is under 4% in general and almost inexistent in IT so wages are up.

The situation in Argentina is good if you get paid in cash because the black market pays twice the official (and artificial) rate. I guess it is not so good if you are being paid through a prepaid card like payoneer.
