While I’m NOT a proponent for UBI, the whole concept of UBI may be in our future whether we like it or not.
As technology continues to replace human labor with robots and automation, we will eventually reach a point where we cannot provide jobs for everyone. Yes, this includes people that make management and technical decisions. Computers will eventually program themselves, they’ll make better decisions than humans, and they’ll even create and repair themselves.
So, what will humans do? Will we live in a society like in the movie Elysium? Basically, if you were lucky enough to be born into a family that has endless money, then you’ll thrive, if you are unlucky enough to be born into poverty then, in this future automated world, there may be no way for you to work your way out of it.
We may fix this ourselves through reduced reproduction, war, or one of many other idiotic population reducing actions.
Basically, it is entirely possible that someday only a small percentage of humans will actually have jobs. Does that mean that everyone else starves?
And it gives modern leftists funny ideas about distributing that wealth to the nonworking long before we ever get there.
