I think the underlying issue even above that is we've automated away the need for workers, yet people still exist. So let's say our economy only really needs 100 million people to do stuff and there are 150 million people, that's an obvious disparity. What really sucks is automation is cranking up but the next generation will be even bigger than the Millennials, which were much larger than GenX. So in the next few decades we'll have 160 million people and only need 95 million people, etc. This will keep happening until something breaks. At some point crimes of desperation will become rampant.
