Universal Basic Income can never happen under Capitalism. It’s impossible. Were it to happen, it would literally collapse the system. Unemployment and the threat of such is the engine that keeps people in the wage slavery grind. Take that away and nobody would opt to be a wage slave as opposed to just coast on UBI and enjoy life. And even if not everyone took the UBI route, the remaining workers would have so much bargaining power, they would dictate terms to the bosses, and we can’t have that.
Stop thinking UBI has any chance of happening in any large scale.
your idea of “basic necessities” seems to be punitively spartan. Surely after rent on a small apartment, electricity, food that’s neither foie gras nor Nutriloaf and such, you’d have a small amount left over, which you could use to have a drink, buy some apps for your phone/computer (and one of those would be considered a necessity), rent a movie, or similar. It wouldn’t be extravagant, but it wouldn’t be some kind of puritanical dopamine famine either.
Unless, of course, the system is run by puritans who levy a tax on joy itself for ideological reasons, in which case living in any state above a sort of suspended animation without working would be a crime. If tabloid newspapers were responsible for the design of the system, we might see that.
Personally, I like foie gras, French wine, and/or a good cigar. There is a real level of artistry in making some of these things, and I enjoy appreciating it.
Once we start trying to categorize which luxuries are reasonable, there is bound to be disagreement. If I want rarer luxuries, I would want the option to be able to work for those.
I still very much agree that there should be a basic quality of life that is socially funded and assured for all people.
