The movement of information and technology from the First World to various Third World countries has created a general "aspir(ation) to First World living standards". The Third World has lower living standards as compared to the First World. Information about the comparatively higher living standards of the First World comes through television, commercial advertisements and foreign visitors to their countries. This exposure causes two changes: a) living standards in some Third World countries rise and b) this exposure creates hopes and many from Third World countries emigrate – both legally and illegally – to these First World countries in hopes of attaining that living standard and prosperity. In fact, this emigration is the "main contributor to the increasing populations of U.S. and Europe". While these emigrations have greatly contributed to globalization, they have also precipitated trends like brain drain and problems with repatriation. They have also created immigration and governmental burden problems for the countries (i.e., First World) that people emigrate to.
