TomSea observes:
"Also, very much in the news have been stories that Japan is depopulating, losing its population."
This doesn't hurt Japan.
It may even HELP Japan.
For the last 40 years or so, Japan has had overcrowded cities, with out-of-the-stratosphere prices for housing in urban areas.
A lower population will put a -downward- pressure on housing, making it more affordable to the young Japanese who will be coming along.
A lower population will put an -upward- pressure on wages (the "robotization" of industry notwithstanding). Fewer young incoming workers means companies will have to compete for those who are available and qualified. And of course, they will do so by offering higher wages.
So long as the Japanese prohibit almost EVERYONE from "becoming" Japanese;
so long as they restrict immigration;
and [most importantly] so long as they restrict muslim activity within Japan, they "have a future" as a -Japanese people-, even if their overall population decreases to one-half of what it is today.
In the meantime, we here at home are being destroyed by tidal waves of immigrants who are (by design) "not like us". And WE ARE THE ONES WHO ARE PERMITTING IT TO HAPPEN.
One hundred years from today, there will still be a Japan.
But what will THIS country be like, by then....?
