The Z-man considers automation, people who can't work even if they want to, universal basic income, and its income on inflation. All those things are very important, and you should go read what he has to say. The real sting in his article comes in the tail.
The truth is, the zeroes that our rulers will be forced to address are zero population growth and zero TFR among the surplus populations. For example, you could fix Baltimore in a generation with mandatory Norplant for the underclass. A generation of childless females means the last generation of 80 IQ residents with a propensity for violence. The reason Baltimore is a violent city is not an excess of hard working, college educated STEM workers. The reason the city is a violent mess is the surplus of violent stupid people.
It also means zero immigration. When 80% of today’s immigrants end up on public assistance, the immigrants of tomorrow will be nothing more than useless people to police, feed and house. Japan is the model to follow. They have no immigration and their population levels are about to drop in the coming decades. They are the only nation on earth that is truly ready for the automated future, as they have the demographics to meet a shrinking demand for labor. They also have the cultural confidence to pull it off.
There’s one other zero the West will have to tackle and that is zero participation. The fact is, free-market consumerism and mass democracy work when the right answer is not obvious. As automation takes over more and more tasks, the number of issues that need to be hashed out collectively will diminish. Rule by robot means exactly that, which means voting and popular government will have to be reconsidered. What’s the point of being mayor when there are no more patronage jobs to dole out to friends and family?
There's more at the link. It's far from politically correct (of which I approve), and particularly sobering to those of us who are (legal) immigrants, including myself. Very thought-provoking indeed.
