Keep in mind that this young man will most likely support his family in Ghana by giving money to his brothers and sisters and acting as mentor to his nieces and nephews. Here's a hypothetical question: Suppose there is a charitable foundation that identifies 100 poor, smart, hard-working young people in Ghana. Of these 100, the foundation randomly chooses 50 to receive a scholarship to immigrate to a rich country like the US or Germany and receive a university education. Ten years after they graduate, the foundation asks an independent person to make an assessment of 'contribution to Ghanaian society' for (a) each family member of each graduate; (b) each individual who did not receive the scholarship and each of his/her family members. If the result is that the estimated total contribution by group (a) is bigger than group (b), would that change your mind about emigration being a loss to the community?
