Meanwhile there's a weird undercurrent of racism, if we just take Japan 2016 and person for person swap out for obviously superior foreigners (imperialism?) then magically everything is supposed to be better. However, in reality, that would obviously not be the case. If an Asian guy is sitting in a broken car, and the driver is removed and replaced with a foreigner, the car is still going to be just as broken. Likewise if the Japanese abandon their land and culture, that doesn't mean anyone else will necessarily do a better job of running the place. Or if there is a better way to run the place, they could save everyone a lot of bother, and implement it themselves.
