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.
I could agree with you more on legal immigration if it wasn't for the illegal entries, it's too many people coming in at once.
