Take your childbirth example: mortality rate may have improved. This statement is great without context – of course thats improvement right?
Now take the context of forced sterilisation and forced abortion by local corrupt government meeting birth quotas. Thats perspective.
What do you base your perspective on?
(In response to your question on N.Korea, I don't know anything about North Korea so of course not!)
>Let's say I consider this prison to be an improvement to me dying of hunger, then would you be able to accept my perspective? Or would you consider me brainwashed?
I would consider you in prison. I would also point out that the prison (government) created the great famine (that made you hungry). Do you really believe that is improvement?
