The problem that UBI has at its core is that it is wishful thinking.
Or maybe, "magical" thinking is a better term.
The proponents believe that all that needs to happen for goods to show up is for someone to pay for it.
And thus, magic money, if created will be adequate for those goods to show up.
But, this goes against the nature of man, AND the nature of energy.
This should go without saying, but those who believe in magic thinking refuse to acknowledge this fundamental force of nature.
If you can buy it in a store, some people put a lot of effort into getting it there.
Not only this, but there was a great line of inventors and engineers that invented the product and the means by which to produce it. Before the factory workers (or robots) even started.
And all that effort needs to be rewarded.
It is also beneficial to reward based on how much the person created.
Time and time again, money that is created out of nothing has returned to its intrinsic value, zero.
A money has to have a solidity to it. It can only change in value slowly over time, if at all.
Most of the UBI proponents imagine a crypto-currency that just issues 100 coins to each address each month. And this is really easy.
However, the hard part, the part that Satoshi Nakamoto said about bitcoin, "now all we have to do is give it value".
Something that is given away for free has little or no value.
It has even less value next month, because the number of tokens is going to double.
Half of nothing is less than nothing.
So, the proponents of UBI believe, like the Weimar Republic and Zimbabwe that you can print yourself to prosperity. They want a crypto-currency that does not implode while it is rapidly inflated. All the ones that tried this before imploded... maybe the next one won't.
And this is the thing that UBI proponents really miss. They say, if everyone was altruistic and just worked, then everyone can have everything. But this has never worked. In fact, it rewards laziness and sloth.
In the USSR, a quote from a worker, "They pretend to pay us and we pretend to work." Yes, the workers got paid... but the money didn't buy you anything. It only bought you what was available on the shelves, at that moment. And that was after standing in line to get in.
In all the pictures that communists love to publish, you see the employer getting all the money, and the employees all getting nothing. Then they show you >> COMMUNISM << where everyone gets an equal share. And, wouldn't that be glorious?
Except for reality. People are different and have different skills.
In reality, 80% of the production is done by 20% of the people.
The remaining 20% of the production is done by the rest. (Its the Pareto Principal)
What happens in a communist or socialist system is that those really productive people are disincentived to produce. Meaning, you do with only 20%. That is the maximum production.
So, in the end, you have the purveyors of UBI creating magic goods paid for with magic money. And what this reality looks like: Go to a store, now imagine that 4 out of 5 shelves are bare. That is all the choices you have. But hey, you got some magic money to buy it with, but it will only buy you half of what it did last month.
Welfare has not made wonderful glowing places for humanity. In fact, it has turn many places into slums. It has destroyed the family, it has destroyed the production, it has destroyed the dreams of countless men.
Many UBI proponents say "we will tax the robots." However, what you tax, you get less of. It is an economic law. So, what you will see is less factories and no incentive to robotize any factories or set up new robotic factories. Why bother when you won't get anything for all that work. And let me tell you, that 80 hour/week work schedule at a job has nothing on setting up a new factory.
Imagine going to work where you might get paid a lot three to twelve months from now. And then, all of sudden, the taxes change, and you won't be get any more compensation than you would flipping burgers for all of this intense effort. Honest question, what would you do?
What happens is that industry stagnates, and then begins to rot. Innovation comes to a stand still.
Even worse, is the hearts of men are broken. There becomes very little to better their lives. Suicide rates shoot through the roof.
But, the UBI adherent says, they can find happiness elsewhere. But, this is not really the case. Man is happiest when he is creating a better future. And when you block that future... wait, the UBI person says, we aren't blocking anyone, we are setting them free! But, they do not see. The long chain of industries that are required just to bring bolts to the store. When you impose UBI on the population, all of these chains break down. You can't get the parts you need to build anything. I guess, you could go digging in the ground for iron ore, coke and coal...
And so it is, UBI proponents have magical thinking.
That this time it will be different.
That people will continue working hard with no incentive and
That money will remain stable while they print a shit-load of it.
