modern day Japanese (Yamato) were invaders from probably Korea 1,000bc, displacing and marginalizing the Ainu and others.
Ok so Japan's immigration policy is a punishment then.
It's not Japan's policy.
It's
a globalist idea "Japan's" policy.
And yes, it's punishing the Japanese for colonialism. Because we all need to be ashamed into extinction for our colonial past.
Oh wait, no, we don't. Because the West abolished slavery, and parts of Africa still do it! Because parts of these so-called oppressed colonized countries were formerly headhunters and cannibals, and sometimes reverted after the missionaries left. I don't have to apologize to fucking barbarians for their wretched sinful ways, I can be proud of my culture and how it tried to help the world.
Then that help was rejected in favor of corruption. Marxism.
Zimbabwe is unbelievably poor. Why? They have literal gold in their backyard. Great. You can't eat gold. Fire the farmers that are white (or even successful blacks), and food becomes unbelievably expensive. Inflation is scarcity. When everything is scarce but money, money buys nothing. Their corrupt government is rich on paper. But here's the thing about paper.

Paper has to be backed by actual goods. Not even gold backing is any good if there are no products.
