Wow that sounds like exactly what's happening in Somalia now. They're miskeen refugees who open up their little restaurants and dental clinics. I hope the government realizes before they start demanding more power
It is too difficult for any group to financially dominate in Somalia. This is because Somalia already has a business class with numerous multi-millionaires. Businesses like Dahabshiil, Hormuud, Premier Bank etc are the reason why Somalia has a growing economy despite virtually no foreign investment.
Haiti and other African countries fifty years ago had no established business class that were enacting projects or providing services in the community like Somalia has atm.
