The percentage of the global population with fuck you money is so vanishingly small that a nation of 100 million such as Japan, could import them all with almost zero impact on their culture.

Furthermore, it’s deeply disingenuous to suggest that inconsiderate people only exist on the upper end of the income distribution. Assholes who want to take over and control others are found at every income level. If you want to keep your country from descending into Marxist dystopia then making fuck you money a requirement for immigration is not a terrible idea.

Well stated
