The population of the US is around 315 million. The population of North Korea is around 24 million. [1]
If we divide the number of prisoners by the countries' populations, US incarcenates .69% if their people. Assuming NK incarcenates 175,000, that is .71% of their people. These numbers seem similar enough, so perhaps we should instead look at prison conditions. By all reports, North Korea has significantly worse conditions. It's incorrect to claim that North Korea rulers are "less effective".

North Korean rulers are less effective in that North Korea remains a small, poor, weak country; consequently North Korean rulers are only able to incarcerate 0.7% of a much smaller population. They would be much bigger human rights violators if they were able to establish control over a larger territory that included more people, as the US government has over the past century and a half.
Furthermore, in NK prison camps execution--including child execution--is commonplace. Maybe that will give you a clue as to why their prison population isn't higher.
Grow a brain.
The wars that the US have been waging are fucked up, I agree, but we're talking about the way a country treats its own people.
I don't think the US is perfect, and I readily admit that it has a shameful level of police brutality, but NK is a completely different ballgame.
I'm disappointed at the level of your response.
200000/24,451,285 = 0.0081 2,266,800/313,914,040 = 0.0072
I'd say those are roughly the same - it certainly doesn't support a claim that the US is an order of magnitude worse.
USA: 0.71% of the population NK: 0.63-0.83% of the population
http://en.wikipedia.org/wiki/Prisons_in_the_United_States says, "According to the U.S. Bureau of Justice Statistics (BJS), 2,266,800 adults were incarcerated in U.S. federal and state prisons, and county jails at year-end 2010."
It seems like the United States is about an order of magnitude worse, even if you subtract the tiny fraction of US prisoners who are locked up to keep other people safe. And that's not even getting into how the countries' respective foreign policies violate human rights outside their borders, but I suggest reading http://en.wikipedia.org/wiki/Casualties_of_the_Iraq_War to start to get a handle on that.
It's not that the Korean rulers are more moral than the US rulers. It's just that they're less effective.
