Since I'm also from a 3rd-world country (though I live and work in the US), I will say that if I felt there was a way to make money that Facebook unlocked, I would take it. Making money is making money, as the bill collector doesn't care how you made it. The question is, can Facebook unlock any opportunity that is not already available through regular banking systems or bitcoin? That remains to be seen.
FWIW, I am keenly aware of the history of 1st world countries "helping" 3rd world countries. It's not a pleasant trip back through history, and the world is still actively dealing with the damage wrought to this day.
