it is up to the people of those countries to start thinking for themselves and earn money, but yes if they can start earning bitcoin online that would be a great help for them financially.
Bitcoin is probably a currency like others but earning it online is way easier than other currencies i guess so if the people in poor countries come to know about this so they can get good financial help as you mentioned, i have seen a person who said his monthly salary is $80 and he runs his family with that money so you can imagine what bitcoin can do for people like him.
