I currently live in Sierra Leone working as a software dev, and just came back from an evening jog around the largest diamond mine in West Africa. It's crazy how much pain an misery diamonds have caused to this country. The citizens here in Koidu don't get any of the income of the diamonds, and live it extreme poverty... Meanwhile the guys from De Beers are living bougie lives in their maximum security compounds, with a pool, western supermarket and bar.
