The basic income argument needs to die, it is inherently flawed in almost every respect, at least as society is currently constructed, a few points as to why:
1. Current standard is a 40+ hour work week. Before paying a large section of the populous to not work why wouldn't we move this down to 30 or even 20 hours per week? The labor force is measured in hours and production, not bodies. If you move the standard work week down to 20 hours there would literally be twice as may jobs. That would require some manipulation of the income received for those 20 hours to maintain standard of living, but that's far more realistic and achievable than basic income.
2. Removing a large portion of the populous from the productivity of a nation is, frankly, incredibly dangerous for a democratic state. Why would the productive segment of the population continue to maintain this welfare system? Civil unrest? If we're in that kind of automated society we would have automated policing of the masses already well in place, so good luck with that. Disconnecting people from the economic engine removes society's need for them.
3. I'm becoming distinctly aware of how myopic the proponents of basic income really are to the kinds of labor efforts available in this country. They see automation of fast food restaurants as a threat to the working class, yet across the first world infrastructure systems decay and last I checked we weren't about to let automated systems run heavy equipment and perform installation of piping, wiring, concrete, etc. completely without human interaction. Automated systems are a very long way off from accounting for all the variables in running a trash route in all reality, as no matter how much you sell the automated curb side pickup as a viable notion too many people deviate from the rules in too many ways for an AI to accurately account for it.
No, what we'll see is an job easing. Instead of slinging bags of trash in the back of a truck we now have automated arms to lift and dump cans. In time the operator of a trash truck will have even more AI systems at his disposal to make his job easier, but he'll still need to be part of the process. Fast food machines might remove the need for all but a handful of on-site staff, but that on-site staff will stop slinging fries for minimum wage and start servicing machines for wages befitting someone with greater technical proficiency.
Basic income, at this time, has no real place among the real solutions to underemployment and economic wealth disparity. Those real solutions are:
1. Decoupling healthcare and (ideally) retirement benefits from employers. Employment mobility is restricted and employers taken on additional workload outside their industry of expertise for a basic human right. Not necessarily single payer but a single point source where people can then make their own decisions would get us to where we need to be here just fine.
2. Destroying hereditary wealth. The founding fathers of capitalism specifically spoke to the need for near complete estate taxation to reset the tables for each generation. This is the real source of wealth inequality. Bill Gates making brilliant business moves and becoming the richest man in America isn't a bad thing, he did something exceptional and earned what he made. The Koch brothers or Donald Trump inheriting daddy's millions/billions and using all of the muscle they were gifted to unfairly step on any competition while rigging systems in their favor is a purely bad thing. This taints the entire purpose of capitalism and the power of the free market to self-regulate to the best of it's abilities. To make matters worse, a large portion of the nation's wealth are tied up in the bank accounts of these kinds of people, leading to economic inflation that pushes everyone else down so they can amass a larger theoretical total wealth figure.
3. Begin rolling back the >40 Hr. work week many professionals do, followed by rolling back the "full time employment" figure to 30 hours a week, both while pushing the minimum wage up, but as something chained to regional cost of living. The first item is a cause of significant underemployment in college graduates where a company staffs four professionals working 50 hour weeks to cover 200 hours versus five professionals working 40 ours a week. We have already seen some movement from Obama on this in raising the exempt threshold. The second is where you start giving time back to people to improve quality of life, but it needs to be paired with the third to keep wages at a livable level. The third is something we already have the ability to implement but instead people want to argue over no minimum wage versus a national $15/hr. minimum wage, both sides making no logical sense. The IRS produces a cost of living index for the vast majority of the country already. Calculate a reasonable living wage off the national average, divide that by 40 (initially, when part two above goes in that changes to 30), then multiply by the IRS cost of living index. So if you live in NYC it might well be a $15/hr. minimum wage. But if you live in Bumfuck, Iowa it's probably going to be somewhere in the $8-$10 an hour range. This will push manufacturing back out to the suburban and rural areas for cheaper labor, decreasing inflationary pressure on urban areas.
Basic income is something we might get to some day but that's just one step shy of having replicators in our homes. There are far more reasonable, achievable methods to improve the economic balance and work force utilization in the first world available right now but once again the us v. them narrative of our political discourse has both sides staking out fringe stances and acting like what they're championing isn't unvetted extremism.
