Indeed. We're watching concentration camps form and fill right now in China and nobody cares because it isn't Westerners being "re-educated" and we like our cheap televisions.
To add to the cognitive dissonance:
Which country on Earth has the most people detained both in total and per 100,000?
You live in a country you are expected to obey those laws or the justice system will come after you. It doesn't matter how unjust those laws may be, it's the simple reality of it.
How on Earth do you propose to take away the sovereignty of a nuclear armed state and impose your own legal system upon them? Internet comments are one thing, slightly viable solutions another.
I truly wish the world would do something but the realist in me reckons that even the most pious compassionate people on Earth aren't sacrificing their life quality for people in the otherside of Earth. Most wouldn't be willing to pay $100 more for an iphone given the choice.
It's very easy to write dismissive comments like mine on the internet but it truly is a very difficult problem to even slightly fix these injustices. Most people care right up until the point it negatively affects them.
