BTW have you ever thought about what incredible bad asses people had to be to cross the Bering strait during the ice age with Stone Age tech? We could definitely settle space if we had the will. It’d probably be more comfortable, safer, and easier, even in the early days, than that.
The comment saying immigrants are 98% of the population of the US is not useful because they are people whose ancestors have been their for many generations.
Defining anyone who has immigrant ancestry as an immigrant is pointless. Sometimes it is useful to talk about, say, second generation immigrants, but not endlessly.
For one thing, after a generation or two the culture of people descended from immigrants diverges from that of their ancestors, even if their ancestry is limited to just one culture.
It's self-evident that this difference between settlers and immigrants has a huge impact. Australia, Canada, and the United States are very similar to each other in terms of language, law, economics, etc. But the U.S. separated from the parent society, Britain, 250 years ago. Subsequently, those countries underwent completely different immigration patterns. So why are those countries so similar? It's because of the difference between settlers and immigrants.
19th century Germans and Scandinavians are difficult to categorize. On one hand, the nation was well established by the time they came. On the other hand, they were the original settlers, creating greenfield cities, in large swaths of the country. Depending on how you count them, a majority of Americans may not have immigrant ancestry. But it’s surely a very large fraction.
I don't see how the numbers support that claim.
What percentage of the population would you like to see made up of immigrants? Would you make immigration harder if the immigrant populating was above 1%?
If it got too high, would you start deporting people or forcing native people to have more children?
According to a 2021 Cato survey--which is a pro-immigration outfit--the median response to "how many immigrants should be allowed each year" was 500,000: https://www.cato.org/sites/cato.org/files/styles/aside_3x/pu.... If we enforced that number long term, we'd probably end up with a foreign-born population under 5%, as we had in 1970. That seems like an appropriate number to foster cultural homogeneity and a high level of social cohesion.
Just tell me, have you ever gone through it? My guess? You haven't as you would think a little different of how easy it is.
And yes, I have.
