You can make the whole world not poor (and quite a few people not as rich as they are). Solution is simple - allow free movement of goods, services AND people. Perhaps also follow-up with allowing anyone to buy any piece of land anywhere so that rich can also buy up cheaper land (fair deal?). A lot of reasons for conflict (and need to organize around nation states) will stop remaining so important. I guess, one can dream...
There is a finite amount of (usable) land in the world. If it is all for sale, what is there to stop the rich from buying all of it, and then collecting rent for eternity, becoming ever richer in the process? How is a return to feudalism your dream?
> what is there to stop the rich from buying all of it
Isn't that already the case though? I'm not aware of any country that limits how much land a single person can legally own, just prohibitions on which people can own it (i.e. I can't buy land in England because I'm not an English citizen).
I’m not against this a priori but I’d expect this to also generate new levels of inequality. As the rich get access to larger playing fields their wealth can grow that much more. Even if true, whether this is bad or not is probably subjective.
I used to think this way, but I tempered my belief to say that all poor countries need a brief period of extreme free markets. 50 to 100 years. After that, some regulation will be needed to manage the undesirable tradeoffs of that period
