They'll say that the North Koreans still haven't implemented true communism/socialism. You see, real communism is always a step or two away from being created. No one has yet to get it right.
And that’s the lie of the assumptions of Humanism -
that people are getting better and better,
morally, intellectually, physically, etc,
and we just have to get the right ones in charge
with enough power to do what their superior intellect
and morality guides them to do.
