Like all generalisations (even this one) that is completely incorrect. I believe there are a lot of people in US custody who are denied that right?
I'm not saying they shouldn't be where they are, or that they should have the right to leave, but your blanket statement is wrong.
Also see Dmitry Sklyarov for an example of when stepping on the wrong corporate toes can get you into all sorts of trouble in the USA.
Like in every other country? This is pretty much a given, so I generalized within obvious constraints.
"Also see Dmitry Sklyarov"
Yes, that's very bad
I know, and I know that it's (societally speaking) a necessary tool. But many see the rate of incarceration in the US as a massive problem itself.
Note that I in no way compare the DPRK with the USA, I just think that talking in absolutes or framing them as opposites doesn't really help. We got a lot of problems in the west too...
Just see what they tried to do with Assange and Kim Dotcom.
They could've done that countless times with less public people.
This didn't stop US from bullying NZ and UK. NZ police even acted unlawfully because of this bullying.
Nobody has the right to leave NK
That alone says loads.
The most essential freedom is the freedom to disagree and leave. North Koreans don't have that right.
