alt Hacker NewsWhy would they take action to exterminate anyone, when they can simply ignore them and let them live and die in extreme poverty, unable to participate in the economy? The west already accepts this kind of poverty with the sweatshop workers, and nobody bats an eye.
It's just disenfranchisement. Only the people who try to use violence to replace the political leverage they lose when they lose economic leverage would need any action taken against them, and that's easy to justify as self defense.
Because 7.5 billion people with nothing to lose would quickly turn chaotic and mass-murdery. 90% of humanity in idle poverty is impossible to justify, at least today they do something of value that can be used as a retort by the morally unscrupulous. A black-and-white situation where a few get everything, most get nothing and do nothing for anybody else is beyond justifying, so the self-defense argument wouldn't work.
