The problem is outsiders keep messing with them. Oh, you have a drout or a famine and people are dying? Here have a fuckton of food from other countries so you can artifically support your population size. Oh, some foreign power wants to invade your country? Here, some other foreign power(s) will come in, give you a shitload of guns and some training and help you fight them off. Most of your country can't read or write or do science? Here we'll build a school and set up programs where you can come over to the west and learn yourselves some knowledge, so you can have a nice life here in civilization.
I swear, it started back in the colonial days when europe was trying to "help" the "savages" because they chouldn't help themseles. Let's spread some religion too, that'll fucking help. The whole continent would be better off if it was sealed off and left alone for about 400 years so they can work their shit out.
