And I’m not going to be able to argue against your first hand account of rural North Korea.
Unless you are from the US or SK, when things open up a bit more that is looking to be possible again. I would encourage you to try visiting if you have the time and means. Even if we totally divorce things from the politics, there’s a lot of beautiful nature there.
Anecdotally, you seem relatively reasonable and I think it would be an interesting experience.
However, I don’t see the people of North Korea being able to put political pressure on their government to change policies.
It does depend to what extent, people can definitely enact policy change. While all political organizations do ultimately belong to the Democratic Front for the Reunification of Korea, they have multiple political parties under that umbrella that do different on some issues. Obviously they aren’t going to suddenly pass laws making the place capitalist, but they can do and do change some things. The Social Democratic Policy is notably more liberal in their attitudes as it was formed by a lot of the petite bourgeoise. They actually have published journal articles that are critical of the ruling party.
