They actually have a somewhat open door policy for the weebs through JET. If your an American with a college degree than your welcome in Japan. There just aren’t that many of them and those people also don’t tend to have children.
There are a ton of people in the Philippines and S.E.A that would do anything to get to Japan even if the work is hard because the standard of living is so much better, much like Mexicans and central Americans wanting to come to the u.s. They would also be more willing to start families. Like the u.s. though they don’t like brown people and only let a limited amount of them in legally.
You can if the company is a non-profit like open AI. Basically when you take on investments for a company you declare what the goal/purpose of a company is, either to make money (for profit) or for some other nebulous cause (non-profit) eg. Ending hunger or saving humanity from AI. If an investor thinks you aren’t following that goal and are pursuing some other goal then they can sue the company.
Sadly most companies are for profit so they can only be sued if they’re trying to do something that doesn’t optimally make money. So a fossil fuel company can’t be sued for legally dumping poison into the air if it’s the most cost efficient method, but they can be sued if they do a less cost efficient solution that would make air quality better because improving people’s health isnt there goal, making money is.
