> Every single person who is for illegal immigration in the US understands why you cannot just move to New Zealand, for example, to stay and work there without permission
Yes, of course, and this is not contradictory. "American Exceptionalism" means different things to different people, but broadly speaking: as a nation built of immigrants, there's no particular "right" time to pull up the ladder and say "That's enough immigrants now." Most people who support this position (not all, but enough to be concerning), when you peel back the veneer, support it because they want America to be "A nation of X" and America facing the reality of more people with different world experiences threatens that goal. There's a reason the protests in Charlottesville turned from being about the history of the South to chants of "Blood and Soil."
Regardless of what the law says: the reality on the ground is the American economy is relying on the labor provided by the undocumented, and they are our friends and neighbors for years running. Sometimes, when a law bends too hard against what the people actually want, you ditch the law. A government fails to grasp that to its peril; hopefully, it only results in tea wasted in the harbor.
> when millions of people enter illegally, the annual quota for legal immigration cannot be increased
Untrue; these are rules we make up for ourselves. Congress could set the number to zero tomorrow. Or infinity. It's entirely up to us.
> Finally, proponents of illegal immigrants are of the same ilk as those who propose raising tax rates for everyone except themselves
I think we'd have to agree to disagree. I, for instance, am in favor of raising taxes on myself and people in my tax bracket, as well as basically everyone above my tax bracket. No strong opinion on lower brackets. And I do send more than I owe to the government. And buy bonds.
Your meta-argument is "These people don't see the problems;" I think you are mistaken. People see the problems, they just think they're better handled with community service than with truncheons and planes to some other country.
> I break into your home with my entire family while you are on vacation. I start paying the bills; power, water, insurance, heck, I even pay the mortgage.
> Can we all stay in your home forever?
I mean, that's an argument about "squatter's rights," not immigration, but for what it's worth... yes? The law in many states does recognize your right to keep using the land if you develop it and it's de-facto abandoned. If I own so much land I can't use all of it and you find a better use for it, that's on me.
The nature of immigration is so divorced from this analogy as to make it worthless. Try this one instead: You come here, build a house, raise a family. Five years later, I come along and try to kick you out because you didn't cross an 'i' on some paperwork in 2019. Is this just, or should I leave you the heck alone because you're not hurting anyone?
> You don't get to grab things (your iPhone, car, home, residency, benefits, etc.) by force and keep them just because you did
I'm sure you're not arguing "America should be returned to the Native Americans..." But that is the argument you are making here. Are you sure you mean it?
... FWIW, I'm sorry your parents were forced out. In an ideal world, that shouldn't have happened. That would have been, what, roundabouts the Reagan presidency? Reagan's administration set us on the path to where we are today by deciding a lot of laws on the books suddenly needed enforcement where little had happened. To all our detriment.
