Does the "rest of the world" include China? India? The entire African continent? Those three regions alone make up the majority of the "rest of the world", and I'm pretty sure an unskilled laborer from any of them would be delighted to come to the United States and work at Burger King. Even relatively desirable countries (e.g., Canada) have a gross imbalance, on a per capita basis, between people emigrating to the United States and and people emigrating from the United States to their country. The imbalance would be much worse if the United States didn't have restrictions on immigration. People vote with their feet, mang.
