"Emerging market" is a euphemism for "developing country" which is a euphemism for "third world"
Brazil is technically part of the 3rd world.
I enjoy visiting poor countries as much as the next guy. But I don't want to raise my kids there or work there for very long. (Maybe as an adventure in my early 20s)
Like every other normal human, including Brazilians, I want to have a good life. As a highly educated, highly intelligent person born and raised in the 1st world, why should I sacrifice all the comforts and enjoyments of civilization that my ancestors worked so hard for to please some bored blogger?
Would Brazilians sacrifice for me? No. They don't give a fuck about me, and neither does this blogger lady. So I am unconvinced by all the appeals that I go work some unprofitable job in some shithole country because Silicon Valley isn't "exciting" enough.
