While undoubtedly a victory for the US, UK, Canada, and Australia, the brain drain from almost every other nation to rich, English speaking countries poses a problem for the world. While economic development models have shown the incentives for this trend for decades, they also show how it retards advancement in the developing world. How can countries like Malawi or Bangladesh be expected to pull themselves out of stagnant development traps when their best and brightest are leaving for more comfortable and (monetarily) more productive lives in the US? The recipients of these skilled migrants have little incentive to restrict their access to immigration, which would amount to denying themselves a valuable economic resource, and the source countries cannot deny emigration without violating personal freedom and rights. The solution to this problem is as yet unclear, but for more global equality to emerge, the distribution of the most skilled and smart must be more even.
