For most people, and especially the poor, labor is their key asset. The main paths to poverty eradication and economic growth occur through labor mobility so that people can find better employment opportunities. This is why all successful development experiences involve significant reallocation of labor between sectors, occupations, or geographic locations. Yet, mobility of people is restricted by many barriers, from national boundaries to distance and linguistic barriers. Only 3.5 percent of the world’s population lives in a country in which they were not born.
