Same as it ever was

"It is no doubt very desirable that we should hold out as many inducements as possible for the worthy part of mankind to come and settle amongst us, and throw their fortunes into a common lot with ours. But why is this desirable? Not merely to swell the catalogue of people. No, sir, it is to increase the wealth and strength of the community; and those who acquire the rights of citizenship, without adding to the strength or wealth of the community, are not the people we are in want of. And what is proposed by the amendment is that they shall take nothing more than an oath of fidelity, and declare their intention to reside in the United States. Under such terms, it was well observed by my colleague, aliens might acquire the right of citizenship, and return to the country from which they came, and evade the laws intended to encourage the commerce and industry of the real citizens and inhabitants of America, enjoying at the same time all the advantages of citizens and aliens."
"I should be exceedingly sorry, sir, that our rule of naturalization excluded a single person of good fame that really meant to incorporate himself into our society; on the other hand, I do not wish that any man should acquire the privilege, but such as would be a real addition to the wealth or strength of the United States."

This from James Madison, during the Congressional debate about immigration policy in 1790.
