The less people, the less NEEDED tax base. Much of the taxpayer-funded spending is due to the added burden of the additional freeloading population that illegals represent. Don't ignore that the illegals are predominantly non-taxpayers (but for a small amount of sales tax), but huge tax collectors in terms of using our schools, roads, prisons, and other government services without carrying the costs. And don't forget the huge burden that they place on our medical system.
The Hispanic tide at least is Catholic...not muslim...so in that sense we're better off than much of Europe.
Their alleged religion is of little importance if they are predominantly liberal mindset. And given all the freebies that illegals obtain courtesy of the taxpayer, these are a very liberal people. Like most of the left, they violate one of the underlying premises of the Christian teachings; "Thou Shalt Not Steal".
Seems to me that they shout "Catholocism" all the way to the bank.
Therefore, I disagree with your idea of "national interest".
We have much with which to disagree on this particular issue.
America can barely afford to carry our own deadwood - we really don't need to be importing more.
I don't believe that's true in a lot of instances.
Infrastructure, Medicare and related benefits for example.
And since the Social Security fund was used as a piggy bank...by both parties...the money that was used must be replaced to keep it solvent.
Hundreds of thousands of illegal immigrants are using fake SS numbers in their jobs...and no government agency on any level has bothered to check...since it's 'free' income to the feds.
I want to say that the vast majority of immigrants that came to this country during the Industrial Revolution were uneducated and became blue collar laborers...just like the Hispanics today.
My grandfather from Sicily worked for Republic Steel in Buffalo, New York.
His presence wasn't appreciated by large segments of the American population...for a lot of the same reasons you have a problem with illegals today.
Today, his great-grandchildren are business owners and in college. My daughter is in her 2nd year at Yale Law School and her brothers are in Indiana and Emory University respectively.
My point of course is that all immigrants are looked upon as 2nd class people by too much of our fellow countrymen.
My unwarranted advice....pay attention to your own life and family...and demonstrate a love for this great country with which we've been blessed.
