Good and problem in economic, politic and social. In the good things is immigration bring trade, agriculture into Indonesia that develop country and more income by produce goods to export. The problem is immigration brought own culture to share with Indonesian. If Indonesian received more other culture, they will conserve own culture less. And some of these new processes are associated with population migration and social changes that impact on local and regional political processes. And the movement of illegal workers cross border. Sometimes, they harmful to the economy and culture are inferior and causes of ethnic conflicts and political. In economic, if more foreign investor came in Indonesia because of land and resource, money will leak out and made country in problem (import more than export). Other problem is creating the gap in society and ethnocentrism (belief that one culture better than other).
