Serious question: what would it take for a US citizen to move to Brazil and work there? I don't have any idea about the visa intricacies.

Surprisingly restrictive, as (last I recall) Brazil has a tit-for-tat policy against the US: restrictions the US puts on Brazilians coming to the US Brazil likewise imposes on Americans going to Brazil. You can, however, buy citizenship for $100,000 (At least I recall researching this. I can't find a reference for at the moment).

    1. A $50k investment
    2. A job or research position
    3. Marry a brazilian :)
    4. Be over 60 and with +$2000/month income

And there are no immigration quotas.

A foreign developer will probably find a job very easily, but be prepared to live on 50% less.

I'm offering to switch places with you. There are no Apple stores nor Amazon here. We have sugar Coke though...

We do have Apple franchises, and Amazon is coming this year (reportedly) :)

But we don't have Cherry Coke :(

Same goes for Berlin (where I live), plus our Apple store opens in a few months, we will be a Lufthansa hub shortly, and Amazon works well here. There are also tons of hackers and startup events here!
