> Money has a way of disappearing (loan interest, people who come after you because you owe them money, etc.) if you hold on to it, so the rational thing to do is to convert dollars to goods that help you immediately
That's largely just a roundabout way of stealing (if you consider defaulting on debts stealing, which I do in many cases). "If I frivolously spend my money before paying my debts, then I don't have to pay my debts!"
I have a lot of experience working with poor people in Maryland, primarily poor African American women (single moms). The vast majority immediately spend their money as you say, but I disagree they are spending the money on "goods that help [them] immediately". Some tried to pay bills, but were too ignorant to understand what they were paying for and why. They would send money to anyone that sent them a letter with scary red ink on it. Also, counter-intuitively, many of the poor I've worked with had the latest iPhones, huge TVs, cable/HBO, air jordans (super expensive shoes), and other luxuries I myself don't have. You could argue these are "psychological necessities" to keep them from falling into despair, but again, I disagree.
> The solution is to provide stability.
The state of Maryland provides free and/or heavily subsidized housing via HOC and free food via SNAP, yet the recipients of such programs I have worked with still frivolously spent cash on toys and luxuries (not to mention booze, cigs, and lotto) as soon as they got it and were in no way on a path to self-reliance. If free food and housing doesn't provide stability, I fail to see how UBI would (especially considering most UBI checks would be eaten as rent which is largely equivalent to HOC)
> The problem isn't that the poor are dumb or uneducated or something
That might not be the entire problem, but it is disingenuous to argue it is not even a component of the problem. Financial ignorance (and ignorance in general) is a huge factor in inter-generational poverty. I've worked with single African American women who had no idea where their money was going. When I helped them get their accounts in order, we found they were paying Comcast for cable despite not owning a TV, they were paying for all sorts of extraneous insurance and warranties they didn't need because the letters in the mail had predatory "amount due" stamps in red on disguising them as bills, etc.
Self reliance does not just magically happen because of "stability". Even a lot of middle class people are living borderline unsustainable lifestyles, where missing a paycheck would be catastrophic because they went way too far into debt for their .
Paying down debts in the optimal order to get on the path of long term savings is not something you can easily bootstrap yourself into without help. You need teachers and mentors for that.
