And what does their food amount per day or length have to do with me visiting there? If anything, I help the general population by visiting there. Sure, that 2000-3000 euros it costs me to do so doesn't matter much, but the people get to see more people from foreign countries. Maybe it indirectly helps in something, I don't know. What have you done, exactly? And again, as I've previously noticed how people (especially those from US) tell how other nationals are suffering so and so much, and when I've visited there it's been nothing like that, I don't really take everything I read on the internet not so seriously. Usually the people are happy, and would be unhappy if things were different. Other people, especially US ones, for some reason like to think they "know better" and try to impose their views on others.
You're not going to be helping the general population by visiting. The money you spend goes directly to the north korean government and not the people. It's not as if your guide/escort is going to let you interact significantly with the average person or buy anything from them.
If you look at reports and studies by a variety of sources (south korean, us, UN, NGO, chinese, etc), they all pretty much paint similar pictures of what's happening in north korean. I suppose everyone could be lying and you magically have the truth of the situation but it's doubtful. Based on a reasonable interpretation of the reports and evidence, the north koreans do have it pretty bad and aren't doing fine and wouldn't be unhappy if things changed. Honestly, it sounds like you're willfully blinding yourself to the evidence out there or are hopelessly naive.
