Ok, we cant do such an experiment though, as neither country allows moving to either one. Tell me, why doesn't South Korea allow their citizens to even enter North Korea? Surely the freedom and liberty loving South Korea should allow this freedom to their citizens, are they not confident in their absolute superiority?
I'm not a politician of that country. But if I had to guess
Reciprocity
Usually open borders between countries requires a bilateral agreement between the countries to allow that movement. So opening the border for people to get stuck in the other country isn't great. And countries typically don't let that happen.
South Koreans certainly can fly to China and then take the land border into North Korea. Nothing stopping that
Excuses, if South Korea was so damn certain of their superiority, they'd allow unrestricted immigration into the North, afterall, isn't this the reverse of what you're saying?
I'm saying we should do an experiment allowing people to move freely to wherever they want between the two countries. I'm not saying anything else. I'm not making any assortations about quality of life, because it's not up to me it's about the people who live there.
Modifying the countries, or anything else is not my place, cuz I don't live there
Well thats not how real life works, and wondering about such experiments is a waste of time, its never going to happen. The situation with Korea is only resolved through war as long as the US is involved.
