They haven't been solved because we're still living as if we're in a scarce world.
Scarcity is what drives human problems. There are two sheep, three families, and one sheep can only feed one family. How do you decide who goes hungry when no one wants to be?
The reason that we, naively perhaps, thought that an information transfer protocol would solve social problems, is because information; anything that can be encoded digitally, is now post-scarcity. But we never reformed society around the invention of the digital realm, and only adapted our old ways around it. This furthered inequality and unrest, rather than healed anything.
With digital distribution, there are now infinity digital sheep for three families and every person, every man woman and child can have infinity digital sheep for their own. It wasn't naive to think that would reform the world because up until that point, scarcity drove and still drives everything. Macroeconomics has us plot supply and demand on a graph, but doesn't tell us how to reform society when supply goes to infinity. Instead of reforming society like we must, we try and artificially limit supply, enacting intellectual property laws trying to deny the copyability of bits, which is like trying to make water not wet.
Why do we have capitalism? It's a long story, but it was invented to distribute the two sheep among three families with as little war as possible. No one wants to go hungry. And to state the obvious, you can't eat digital sheep. Nor are they created like organic sheep. Many someones have to come together, intentionally, working very hard, to lovingly create digital sheep like Disney's latest masterpiece from raw ones and zeroes.
Those someone's exist in a pre-scarcity world. They need pre-scarcity money to buy non-digital food to eat and pay rent on non-digital housing to live in. Digital sheep don't exist without the hard work of people who need non-digital money to exist in a pre-scarcity world. So we still need the old economy to pay those creators in pre-scarcity money. But once that digital sheep exists, there can be infinity copies of it. Every single person on the planet with a cellphone or computer can have their own copy of that digital sheep for a mere pittance in bandwidth costs.
Until we reform our whole society; the economy and the government; to realize that we live in a post-scarcity world for all digital goods - and are effectively post-scarcity for some physical goods, it's always going to be us in the same place. Poverty, war, man's inhumanity to man, tribalism, they all exist online, but they are different online. People are different because of the Internet.
The reformation we need is going to be radical, because it has to be. Supply and demand just got shot in the face because there's an infinite supply on digital goods. My proposal, in all its earnestness, has a few steps.
1) We abolish copyright. I said it was going to be radical, didn't I? We change systems around so that copying is allowed, but that it tracks what people are watching, and where it came from. But we abolish the system that's trying to make bits not copyable and water not wet.
2) We track what people are watching, and give out points based on that. Every day I'm granted 86400 attention cents, or ACs, and if I watch a two hour long Disney movie, Disney gets paid 7200 ACs by me. Disney gets to further distribute those 7200 ACs however they see fit to the individual creators who made that movie. If I spend 3 minutes chuckling at a tweet or a YouTube or TikTok video or Instagram video, the creator automatically gets 180 ACs from me, which they can pass on to whomever they see fit, literally crediting their sources.
3) We establish an VAT luxury tax, anything that's more than 3 orders of magnitude more expensive than the cheapest one, effectively creating a price ceiling on goods relative to the cheapest version of that same good. The $10 bottles of wine at my local store mean that bottles of wine now top out at $10,000. Anything over that is taxed and goes into an AC fund. Remember, capitalism is just some silly system we've come up with to decide who goes hungry and who gets to eat the sheep. Other such systems include feudalism, where a lord decided who went hungry and who was fed.
4) With that money, we establish an official way of trading ACs for pre-scarcity money, so people can use their ACs to afford non-digital food and housing and clothing and entertainment. Isn't that system going to be gamed and broken and create all sorts of arbitrage opportunities you ask? Yes but have you seen how broken the rest of capitalism is right now?
