That's the question, isn't it? Why not just do that? Who are you trying to keep out of the country, and for what end, and is that end best attained by removing people from the country who aren't the ones you are trying to keep out?
For instance, if you believe the border should be strict to keep out serial killers, what does that have to do with removing Korean car factory workers who aren't serial killers?
Different people are different. Any change in demographics — such as an increase in wealth inequality or number of smartphones — causes a major cultural shift. What is the evidence that this particular cultural shift is very bad?
"major culture shift" != "they will turn your country into the country they fled from".
Regardless, the culture is that of a nation of immigrants. I don't see how anything here can cause major cultural shift away from that. I am willing to bet you won't be willing to elaborate either, so next goal post move please...
I think they’re trying to get you to put on record in print your explicit views. It’s a trap — don’t do it! As soon as you commit to words that you’re exhibiting discriminatory or abusive behavior towards a group because of their race or national origin, they will call you a racist!
So for the United States, it would primarily be family-oriented Spanish speaking Catholics whose kids will be bilingual and grandkids will speak only English? There have been waves of immigrants before where the Irish or Italians or Germans were seen as "invaders" undermining the character of the country. And then their descendants fully integrated and became part of the culture.
Also the US and Western European countries are in much better economic and civic conditions that the immigrants can take advantage of to live better lives and contribute.
Well, if a Korean car factory worker live and work illegally in the country, then it makes total sense to remove them, regardless if they are serial killers or not. A company shouldn't even hire anyone who is not eligible to work legally in the country. There are laws that need to be followed like everything else.
It sounds like you're saying that you want the country to have open borders so that everyone can come live and work here given they pass some basic checks (no criminal history for example). I am not saying that is wrong, but that's not how pretty much every country in the world operates.
