While I am not a nationalist and I think it's commendable that the human race is making progress, I'm concerned that advances in technology are causing troubling concentrations of wealth among those who operate and control the technology.
The cold hard reality is that a lot of the jobs that's been created in the US are wallmart jobs or part time jobs and that the cost of living is going up.
So those who keep mentioning luddite fallacy owe it to explain what new jobs it is they see replacing the current jobs. Because if it's just a hope that it will be all right in the future some day it's not really an argument for anything.
I agree it is a problem that people will be put out of work, but that is kind of an inevitability. Which is why a lot of people are arguing that basic income needs to be investigated much more closely.
The issue isn't The Wealthy having all the money. The issue is technology that will actively remove jobs. It doesn't matter if minimum wage is 90 pounds an hour if you don't have a job. An automated train isn't The Wealthy stealing money. It is a conductor out of work because their job could be handled by a raspberry pi.
Basic Income is a theoretical concept (been implemented in small, borderline meaningless, experiments) to combat that. Everyone gets a bare minimum "salary" regardless of if they work. That covers cost of living (how much more varies). Then, those with jobs have the potential to earn a lot more (incentive to work) on top of that.
What Thomas Piketty proposes wouldn't address the lack of income to those put out of work by technology but could, possibly, help to pay for solutions that would.
Take it a few steps forward. At some point the factory owner (whether local or conglomerate) holds all the money and has 0 workers. The only thing he can buy is new resources to produce more stuff, but no one can buy that stuff because no one works anymore.
At some point it's just a machine making stuff that no one can afford to use other than the very few owning the machine.
Money is useless unless it's spread around and in rotation through the system. The unemployment of uneducated is the one thing I really sympethize with in this election, but the solution isn't going backwards, because there's nothing there anymore.
I understand that the solution isn't one step forward, but maybe 5, and people will suffer in the interim, but that only means it's ever more important to swiftly move in the right direction.
