Two points:

(1) You are correct that you cannot test UBI in a petri dish. It has to be all or nothing to see the REAL effects.

(2) If you rework UBI to be a negative income tax and remove all of government subsidies and handouts then it would have much less potential for disastrous economic impact (see Milton Friedman[0])

I see being an advocate for UBI as advocating for solid answers to those questions.

I would also point out that there's a difference between a full UBI, a modest partial UBI, and the kind of "basic income" that's not universal and goes away at a rate of 50c on the dollar when you earn more, like in this study. You can't slowly roll out a full UBI, but that's definitely possible for a partial UBI or a means-tested cash payment. You can dial the amount down as far as you want and still study the impact.

"inflationary collapse" seems contradictory. I think hyperinflation is a more correct term.

> (e.g. increased velocity without direct economic output)

Transfer payments don't really increase the velocity of money because they're not associated with any direct economic output.

If Alice has $100,000 to spend and Carol has $25,000 to spend, there is $125,000 in actual spending, i.e. demand for something that has to be produced. If you then do a transfer payment of $10,000 from Alice to Carol then Alice is spending $90,000 and Carol is spending $35,000, it's still the same $125,000.

Maybe they'll buy different stuff, maybe one would be more likely to buy business investments and the other would be more likely to buy college tuition, but that has no more likelihood to cause problems than if Carol got a raise and Alice had to pay for it.

If Alice has $100,000 to spend and Carol has $25,000 to spend it's much more likely that Alice will save a bunch of money instead of spending it.

Giving poor people money is much more likely to be spent at all than when you let overly rich people keep it.

What do you expect to happen to money which is "saved"? They're not stuffing it in a mattress. Some business gets it and then spends it to buy inventory or do construction or whatever it is their business does. If it was actually stuffed in a mattress forever at scale then the government would have to contemporaneously print that amount of new money to prevent deflation from the contraction of the circulating money supply, and then somebody would be spending that.

> They're not stuffing it in a mattress

How do people get (and stay, and get ever more) rich if not by accumulating wealth? They aren't stuffing it under a mattress, no, but they also aren't spending it significantly.

What do you expect a millionaire to do if you hand him $10? how about giving a homeless person $10? My intuition is that money is going to get spent a lot quicker by the latter.

We've tried trickle-down economics and it clearly doesn't work. Let's try trickle-up economics for a while, see what that does.

> How do people get (and stay, and get ever more) rich if not by accumulating wealth?

"Accumulating wealth" and "not spending the money" are two entirely different things. If you have a million dollars and use it to build and operate a factory and then the factory makes things you can sell for two million dollars, your wealth has increased by a million dollars, but in the meantime you've spent the entire million dollars you started with on building and operating a factory. And the next thing you're going to do is spend the two million dollars in order to make four.

It's a proposed solution to mass unemployment scenarios.

If the government wanted to give people money right now, it would just lower income taxes.

If you have a better solution to mass unemployment, feel free to share it with the rest of us.

How about... greater benefits to people who are unemployed? I mean, UBI is inherently a poor policy for "mass unemployment scenarios", because there is no feasible scenario in which the majority of people are unemployed. To give UBI to people making around the median wage or higher because there is mass unemployment due to automation that doesn't affect them doesn't seem like a good use of money at all.

"there is no feasible scenario in which the majority of people are unemployed"

Try not to ever forget you said this, you'll find it hilarious in the future.

The value of typical human labor never stops falling, while the costs of employment never stop rising. Something's going to give, and it's not going to be the profits.

why not do it gradually by expanding regional pilot programs, you can't answer these questions without doing it

Another possibility is a negative tax issued every month that becomes effectively UBI.

Also, if the IRS were to cut some of their absurd tax breaks for billionaires like the carried interest loophole, simplify things, calculate it for people, and withhold the most likely correct amount ahead of time, it would ease the unnecessary burden placed on people who aren't rich enough to have tax accountants.

Corporations need to be taxed at around 75% too while we're at it to pay their fair share. The ratcheting of tax brackets should also be 90% of personal income for the 3 millionth dollar and over. Every billionaire is a policy failure and CEO:worker pay exceeding 1000x is crazy.

1. You're fear-mongering and red baiting with strawman FUD.

2. Doesn't have to be that much.

3. Alaska issues a yearly dividend from their permanent fund.

I have a hard time seeing how UBI would be fundamentally different than what exists on American Indian reservations. Is that the model that people are envisioning?

Are you serious? Reservations are employment deserts with little to no opportunity to do much. That, paired with generations of societal genocide, means reservations are not a good test for what can be done elsewhere.

That comparison is absolutely wild.

I heavily edited my comment (a sibling to your comment) to tone down the snark. But I agree - this may land in my top 10 most insane hacker news comments that I've ever read.

Maybe you can suggest examples then where UBI have worked?

There was quite a bit of displacement, subjugation and genocide of entire peoples that precipitated any handouts they did receive. It is possible that that influenced outcomes.

I know my example is flawed, what then are some examples where UBI has worked?

We already have UBI....as long as you are over 65 :-) In addition, I suppose you would agree that children should be guaranteed to have a home and 3 square meals.

So already something like half of our lives are covered by some kind of UBI. 20 years to mature, 20 years of retirement, sandwiching a 30-40 year career.

Don't forget, UBI would replace everything else. Food stamps, unemployment benefits, social security, etc etc. And literally SQUARE MILES of office building staffing bureaucrats who do means testing, fraud prevention, etc etc for government benefits would also not be required.

If you put together all of the money we spend for all of that, I wouldn't be surprised if 90%, or even 100% of the cost of a UBI could be covered.

> If you put together all of the money we spend for all of that, I wouldn't be surprised if 90%, or even 100% of the cost of a UBI could be covered.

Administrative overhead is nowhere near as high as you estimate.

SNAP covers ~12% of the population with 5% overhead costs.

Medicaid covers ~20% of the population with 5-10% overhead.

Social security covers ~20% of the population with <1% overhead.

The extra spending to make benefits universal is an order of magnitude higher than any savings from eliminating bureaucracy.

You're measuring the cost to the government, not the cost to the public. How much time do people waste filling out eligibility forms? What's the economic cost of wastefully converting fungible money into non-fungible requirements to buy specific goods and services?

Meanwhile the "extra spending" isn't real because the benefits, being universal, are going to many of the same people paying for them, and therefore simply cancel out. The purpose of making them universal is the simplification: It's simpler -- and therefore harder to cheat -- to have a UBI and a uniform tax rate than to have a benefits phase out that effectively cancels out the lower rates on lower income people in the existing tax code. Or worse, creates marginal rate cliffs and highly irregular rates because overlapping benefits phase outs interact with each other in random and perverse ways.

You are quite correct that the overhead of most government programs is relatively very small.

But look at your numbers....12% of the population on SNAP, 20% of the population on Medicaid, etc etc.

What would it really cost us to just pay the equivalent cash to everybody, and then raise the taxes to offset the costs on people who don't need it?

We are already paying for--piecemeal and very inconveniently to be sure--much of what we'd want a UBI to give us. It probably would cost us more in taxes than what we are paying for now, but it wouldn't be an apocalyptic increase. The delta of spending is not as big as what one would initially think.

Well, many people are on all the programs, and 2/3rds of Americans get no government assistance.

Thus, any UBI that doesn't cut the poorest people's benefits would cost 3x the current amount.

I don't think a 200% tax hike would be very popular.

I'd trade a 200% tax hike for a guaranteed $3k a month.
