A million a year plus massive illegal immigration is an enormous amount for any country to take in. That reasoning, which we hear frequently that it's small in comparison to the population can also be turned around to highlight how those same percentages could mean 10 million annually in China, or 1% of a billion. Do you think China needs another 10 million people a year added to its population ?
In 1924 we gave mass immigration a rest and it's long past time to do it again. That legislation proved to be very successful at assimilating those immigrants into the mainstream of American life.
Ya when you add in the illegals coming in its pretty substantial the numbers. I've seen estimates of legal immigrants, plus illegal immigrants could be as high as 4 million coming in last year. But it could also be like 1.5 million.. no one really seems to know.
The conspiracist in me says that the ultra elite people in America view having millions of people in the country who have no legal rights as very useful.
