I apologize to Korea
I must admit I hadn't noticed it, and I studied the Korean War in history class!
It is true that Marxist countries normally emphasize their democracy and the fact that they are for the people. This is the theory of Marx, and the proposed outworking of socialism. In terms of communism, we all know that that didn't quite work out as it was planned to by those who tought it up- it was hi-jacked by some very crazy, very evil men.
Westernised (capitalist) countries generally don't bother to emphasize their democracy. And being about the people is not what capitalism is, per se. Although, ironically, a lot of people would argue that it serve the people better.
I am a socialist in political persuasion, but am a capitalist in practise. that is the nature of the place i live and the world I grew up in.
