This is where America is heading. Japan doesn't like immigration just like the r's. To combat this, r's are trying to force young white women into having unwanted babies. Also, it's a little hard to do war without a population to send.
Germany, North Korea, Denmark, and a bunch of other countries too. Yet somehow they manage to blame "immigrants" for their childlessness, not the rich, powerful, and wealthy who make the country unattractive to have children in.
If you have a degree and come from a number of countries, that's about all it takes to get a work visa. For English "teaching" (most jobs are glorified tape recorders from what I've read), you don't much at all. I've been here almost 10 years and will be applying for my permanent residency shortly. Since I've come, they've actually made it easier to get PR, especially for younger people, with points systems.
