Yes and it will just need a light dusting in a few decades and then a new people will be able to move in.
Man, Japan is really missing out here. They should listen to the wealthy western champagne liberals on HN who are outspokenly pro mass migration and yet spend most of their income to live in homes as far as possible from cities impacted by mass immigration, usually in majority-white suburbs with good safe schools and manicured lawns.
Edit: answering here to your comment below. Which statistics are you referring to? And why is resorting to the Hitler card on people who disagree with you your only argument? Let's address your vile accusations with facts from experts:
"Harvard political scientist Robert Putnam -- famous for "Bowling Alone," his 2000 book on declining civic engagement -- has found that the greater the diversity in a community, the fewer people vote and the less they volunteer, the less they give to charity and work on community projects. In the most diverse communities, neighbors trust one another about half as much as they do in the most homogenous settings. The study, the largest ever on civic engagement in America, found that virtually all measures of civic health are lower in more diverse settings."[1]
It's certainly a purely theoretical fate. I have zero reason to believe undocumented people are more dangerous than citizens. I mean, intuitively, they risk so much more - namely deportation and torture. If I followed a Republican philosophy of tough on crime, I would then say they must be committing less crime.
Do we have any reason to believe they're more dangerous? And I mean real reasons, like statistics. No Patrick, "they're vaguely brown" is not a real reason. No Patrick, "homogeneous population" isn't a real reason either.
That's a really different thing than one million people illegally entering the country and expecting that to just work out. Can you imagine the response Japan would have if a million Americans crossed into Japan illegally and expected to live and work there?
Bingo. So why are some western countries supposed to tolerate this?
Sure, but this isn't my point. Nobody has given me any reason to believe it won't work out, included our undocumented immigrants. I live in Texas, I should be seeing the worst of it. But uh... no... everything is pretty chill here. Not really seeing any of these doomerist complaints about those darn illegals.
> Can you imagine the response Japan would have if a million Americans crossed into Japan illegally and expected to live and work there?
I sure can, it would probably be piss-poor. Because Japan has a strong ethnic identity and community-oriented culture. We don't.
We're not Japan, nor do we really want to be Japan.
Nation wide policies and society don't work on how your own chill vibe feels where you live, but on research, statistics and most importantly on the opinions of the democratic majority.
