JD, to be fair, you said, "... who else proposed something similar to that in Germany during the 1930's?".
DT has never proposed anything of the sort. He's consistently said that he's not against immigration, just that it has to be legal.
Our leaders here in Oz have said the same thing - that peeps are welcome to come here but "only in a manner of our choosing". I equate it to running a "decent" nightclub. The bouncers are at the door for a reason.
Besides all this, the sentiment is actually expressed by, for example, Latinos who're living in the US legally. They themselves had to wait up to 10 years for approval and whatnot and become incensed at the idea that peeps can just waltz in over the border as they please. I can relate to this; my family had to wait 6 years for approval when we emigrated here from South Africa.
Almost nobody hates illegal immigration more than those who obeyed the law and stood in-line for God knows how long.
FWIMBW the adherence to the rule of law, the degree of patriotism (in the good sense) and so on tend to be very-high in individuals who took the hard, legal road to their destinations. They make good citizens and taxpayers. A much-larger proportion of unregistered illegals do not and of course you have all the attendant problems such as censuses meaning nothing, which affects infrastructure planning and so on. Not a huge deal when you're talking about a few thousand illegals, but tens of millions? Not so much.
All this and not to mention the strain on the health system. It goes on-and-on, which is why "civilised" countries enforce their borders and require vetting of potential immigrants. I mean, duh. I'm 100% sure you know this.
Just my 2¢ worth mate.
