Nonsense. You don't need to look at any other place that you might not agree with to understand the effect of negative influence. High chances are that the person who said that has never even been to North Korea.
Learn about negative influence; that can give you a clue of how that can happen right in your own home, no need to look at other people's ideas of how people live in other countries.
