There's a lot of skepticism about basic income, especially when it comes to how does it save money? The top comment as of this writing is questioning it:
> But riddle me this: what do you do when someone on BI has a financial emergency or, as will happen with some regularity, just flat-out blows all their money and now can't afford rent and/or food? Do you tell them "tough shit, you've exhausted all your social safety nets" or are there safety nets below BI, essentially recreating the welfare programs previously destroyed? If so, how do you prevent fraud without a department following up on Joe's twelfth "my car broke down" case of the year?
Allow me to digress for a moment, I've recently been reading "The Expanse" series, and they have a throwaway snippet in the second book (i.e., not a spoiler) where a Martian Marine is walking the streets of a city on Earth. There's a girl who sells her a hot dog. The girl says that she's doing it for work credits. After she accumulates one year worth of work credits, she can attend university and get a real job and make money. Otherwise, she'd have to be "on basic."
Like I said, it's a throwaway scene, so there's not a lot of detail, and even in the later books when they talk about being "on basic", it's not a detailed description. But the girl in the story distinctly mentions "money" after "getting a job" which came after "university." That implies to me that, on some level, money doesn't exist for those "on basic." (And to be clear, in this not-terribly-futuristic Earth, everyone's on basic.)
In other words, the term "on basic" implied to me that you get food, shelter, clothing, access to public transportation, K-12 education, healthcare, and basic internet automatically. But if that's the case, why would anyone want money? Well, the implication here is that the food is minimal: ramen noodles and vegetables and beef. Shelter are studio apartments. Clothing are Wal-mart quality. Basic internet is more like 56K than broadband.
In the Expanse Earth, if you want more than that minimum (and most of us would), then you have to spend a year working to prove your willingness to contribute to society, and then you can go to university for free, then get a job and make money. That money can buy you things like a house with a yard, a car, surf and turf, and vacations to the moon.
If we were to somehow (and that's a big if) go with the definition of "basic" from The Expanse, it's almost impossible to squander it. You aren't handing Joe $500 and saying "This is your money for the month. Don't blow it." The food and clothing are free. (Presumably with demonstrable need, but in a post-scarcity society, perhaps T-shirts cost virtually nothing compared to the previous welfare systems and you might as well just hand them out on demand).
I'm not an economist, and I don't know the ins and outs of basic income, but that one throwaway page in The Expanse made me think a lot about what I think basic income should look like... and I don't think it should look like a monthly check.
