"We all of us know down here that politics is a tough game. And I don't think there's any point in being Irish if you don't know that the world is going to break your heart eventually."-Daniel Patrick Moynihan, December 5, 1963
He who knows the least obeys the best.
Anyone who is in touch with reality and the daily news knows that people are coming to the USA with or without permission.
I doubt that telling them to stop coming will have any measurable effect.
The only way that the USA will ever slow down the flow of these people into the USA is by putting better security in place at the borders.
I predict that will not happen anytime soon because of the monetary and political costs involved
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
Cicero Marcus Tullius
These are the symptoms of liberty, not the causes.
And as for things like food-stamps and the nationality act of 1965, those are but minor details in the grand scheme of this country being a beacon of hope and freedom for people all around the world. This is truly a place where ANYONE can come and make something of themselves.
In my opinion that is the single most important attribute of the United States.
An extremely simple border system seems to work well within Europe. Why should it not apply here, especially where so much of our border(s) are extremely harsh, rural and difficult/ expensive to patrol. The billions spent on border protection would me much better saved or spent on local communities.
