I'm an immigrant myself (a legal one), yet I'm forced to agree that the sort of almost unfettered immigration (legal and illegal) that both Republicans and Democrats have encouraged and fostered over the past two and a half decades may be the single biggest threat facing the USA in the long run. That's because of the cumulative burden it will place on our infrastructure and institutions. It's why President Trump is right to want to get rid of all illegal aliens within our borders - and why he hasn't yet gone far enough, in that he hasn't sought to cut back on legal immigration as well.
Readers may remember this presentation, which I put up some years ago, about how the USA cannot solve the problems of the Third World by allowing more immigration from those countries. I recommend watching it, and the following video clip, in full-screen mode for maximum impact.
Here's the same man, showing us what immigration will do to this country over the rest of this century - unless we do something about it.
Scary, isn't it? - yet his numbers are direct from the US Census Bureau and other authorities. They're official figures, not made-up statistics. What's more, both presentations date from 2010. The situation has grown much worse since then, particularly because the Obama administration turned a blind eye to millions upon millions of illegal aliens pouring over our southern border.
It may seem odd that I, an immigrant, am encouraging a harder line on immigration; but I've assimilated. I'll always be grateful to this country for giving me the opportunity to make a fresh start, after many years of conflict. My perspective isn't based on an attitude of "I've got mine, Jack - you're on your own!" It's as an American, even if by adoption, that I say, in all honesty and sincerity, that we need to encourage President Trump and our legislators to get serious, both about kicking out illegal aliens, and cutting back on legal immigration. The survival of our country as we know it is, quite literally, at stake.
