I hire developers in Brazil and travel there on a regular basis, in fact just two weeks ago I was in Campinas and Sao Paulo visiting developers I had previously hired and they live much better than I do despite making half what I do. 

If you're a half decent developer you should be able to double your current salary by working for US based companies as a contractor. I believe there's even a significant tax loophole that you can take advantage of if you work as a contractor exporting services.

I'm live in Campinas and I'm from São Paulo funny to find someone who knows here in WSB of all the places. 

I'm a officer in the Brazilian army, head of a developer team, but because we have a 8 year contract I still can't get out without have a huge financial loss for leave before my time.

A dev here making $45,000 a year live a equal of someone doing $120,000 (after taxes) in the US.
