IMO, the problem with this in RL is that it's just a "rich" man's experiement in the western world. Half the world is poor and can't afford most things, because they can't even cover the costs of production, transportation, and distribution. Not to mention the added profits on top, before the product is available for purchase. So simple logic says that to make an equal system work you'd have to minimalize or remove as many as these factors as possible. Technology can help this process a long way, but we aren't ready yet.
Free trade is the answer. 30 years ago Indians toiled away in ‘sweatshops’ stitching trainers and western do-gooders campaigned to get these ‘sweatshops’ closed down. But they used their wages, which were 5x what they would earn working in a field under the sun, to educate their kids. Now the west outsources their IT development and call-centres to India, they use the money to develop a middle class, and their kids will be even better educated and ever more able to prosper.
A few years ago a prominent charity campaigned to get Indonesian ‘sweatshops’ closed down that employed children. They succeeded. When they returned a year later to their horror they discovered most of these children had been forced into prostitution to survive. They presumably just assumed that children not working would be at home on the Xbox or something. So don’t listen to do-gooders, they just make everything worse.
Indeed, thank God for the rich westerns, who buy stuff, that is made abroad, and create jobs, and those jobs set of a spiral of economic improvements that creates an Asian middle class, and more trade, and more jobs and so on as billions are lifted from poverty. You say half the world is poor, maybe, buts that’s better than 75%, and if free trade continues in fifty years it will be 25% of the world is poor and so on.
(Well, the lefties will just keep redefining the term ‘poor’, but you get my point. Real poverty is shrinking.)
