Alternatives are better  There are alternatives to the repatriation of illegal immigrants that are much more attainable. First of all, there has to be more attention to the root causes of migration, rather than attacking the results. The money that would be spent on repatriation could be used for prevention of immigration by focusing on border controls and improving economic conditions in countries where migrants come from. Trade agreements between developed and developing countries could be improved, which gives poorer countries more opportunities to trade. Most illegal immigrants migrate to Western countries to earn money, so if there are more opportunities for foreign workers to operate legally and on a temporary basis, with the assurance that they can come back if needed, this will remove the current incentive for many illegal immigrants to stay in their host country.
