Bought a used one for ~60 bucks. Has worked for a long time. If we assume that increased scarcity increased costs by 12X (not your 3-4x), I could still afford it on the dole. And if I couldn't, I'd have to do without. End of story.
Have you ever purchased various widgets/cups/clothes at Target or Walmart?
No. I deliberately buy expensive goods that are made by union-driven companies.
Ever check the "Made in X" sticker of those?
Yes, I track this. Above, and for the record, I've been researching my purchases for 10 years at this point and continuously do so.
And keep in mind, even if you are wealthy enough to afford more expensive products, the vast majority of people have experienced meaningfully higher qualities of life by purchasing products assembled in countries with fewer protections for workers/labor not to mention lower cost of living.
So again, my point is that just being "pro-union" or "pro-labor" is myopic in the extreme unless you acknowledge that this position represents a trade-off between the consumer and the worker.
There's a trade-off indeed, and I acknowledge that, but calling me/inferring me to be a hypocrite is nonsense and honestly isn't important to the discussion. Personally I buy very little. I'm actually on the lowest income bracket and still afford what I need. In Denmark, where everything is incredibly expensive. (The Target/Walmart point is off here and kind of weird, since you know, not all people live in the US? Still, what I'm saying holds true in the equivalents of my country).
The point is the trade-off and the overall economy, not my personal consumption; if it were the latter, there would be no argument. Not everyone is in my situation and not everyone has the mental resources to thoroughly research what they buy.
So if we could get off my back, please, and talk about the more general situation, in which, yes, I still think cheap smartphones made off the back of slavelike conditions isn't acceptable. We've only had smartphones for, what, 10 years? 15? This is not an eternal status quo. There are ways to work with it.
Again, I'm biased here, based on my personal consumption, which is quite union-friendly. Which is why I'd rather talk about a general picture.
EDIT:
I see that you support UBI, which I do as well, however I'm tentative about it, as UBI is still a novel idea with little practical evidence of working. But I do support it. I do think, however, that unions are a more immediate, established solution to a lot of the problems the modern West faces; if anything, I believe the Danish model is reasonably succesful. Would I throw that away for a straightforward UBI-based model? I don't know. I want to know, I want to support it, but I don't know enough. Too much theory, too little practical application (so far). And I need to eat.
