Bush has this issue right. Re immigration:
Have we stopped to do an accounting of what immigration has done for us on the plus side of the ledger?
First, US native population is dropping. That is, the number of babies born to those born here is not keeping up with deaths. Its the same worldwide in the industrialized countries. Since a falling population is bad for the economy, a liberal immigration policy has been adopted by these countries because it makes wise economic sense.
Second, and most obvious, immigration builds a hidden savings into many businesses across the entire spectrum of the economy. What we pay for most services would go up across the board if employers could not get access to cheap labor
Third, what is a wall at the border going to cost us to build and maintain? As with most government construction projects, it will come in way over budget. And then there?s the cost of having to police the wall.
Finally, health and education costs. Educating people never costs, it pays. Large masses of uneducated people are a bad thing. And as long as they are here, let?s make sure they are healthy, and not spreading disease and illnesses. It?s the least we can do for them if we insist on hiring them to pick our fruit, clean our houses, and prepare our food.
Lets not forget the example America sets for the world.
Not like the brazen giant of Greek fame,
with conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
a mighty woman with a torch, whose flame
is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame,
"Keep, ancient lands, your storied pomp!" cries she
with silent lips. "Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore,
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!"
Emma Lazarus, The New Colossus, 1883
