An important point to make, I think, is that immigration is what made America the greatest nation in the world, and immigrants are a huge benefit to the United States. Economists uniformly agree that immigration boosts the economy. Even an economist opposed to liberal immigration laws admitted that immigrants increase the GDP by $1.6 Trillion, benefitting both themselves and everyone else. If we severely restrict immigration, we can look forward to becoming Japan, a stagnant nation slowly dying of old age.
