No, America was built by settlers who ruthlessly hacked civilization out of the frontier for the benefit of themselves and their descendants
Jefferson warned against allowing immigration from lands so wholly foreign to America and her culture as France and Germany in his Notes on the State of Virginia because he recognized that the unique American spirit is what made America great and diluting it would make America less great
To the extent that immigrant groups made America better, it was because they assimilated into American culture first, and became Americans
When the first big wave of migrants that utterly refused to do so showed up from Central and Eastern Europe around the end of the Gilded Age, the chaos unleashed was so disastrous as to lead to the 1924 Immigration Act, which deported as many of them as possible while sharply limiting immigration moving forward
Hart-Celler then undid that and flooded the country with even more foreign migrants once again, and things have been getting worse and worse as a result
America was built by the world's greatest and most driven immigrants FOR the world's greatest and most driven immigrants.
Yes, yes... the border should be secured, and there should be zero illegal immigration -- we're all in agreement on that.
And we should seal that border so we can RECRUIT the best and brightest people from around the world, especially from our rivals like China, Russia or Iran.
Every time an elite performer switches teams and goes from an authoritarian country to the world's greatest democracy, America, that is a major win for humanity and freedom.
Note: these individuals must commit fully to assimilating into the American way of life and be part of the "Great Melting Pot."
Finally, there is the issue of full employment for Americans. We are at the lowest unemployment of our lifetimes right now.
This is as good as it gets.
We shouldn't be using the H1B visa system to replace Americans with cheap labor, as I've been saying for over a decade.
I'm extremely happy that President Trump took my suggestion to put a massive tax on the H1B program, because once you add $20,000 -- let alone $100,000 -- to a visa, you get rid of all the folks trying to hire $50,000 IT folks from India to replace $75,000 ones in America.
I saw H1B abuse firsthand in the 1990s when I worked at SONY -- where the IT department used the program to create indentured servitude.
It was cruel and disgusting then, as it is now, and it should be called out now and stopped.
