Weird Weather? Or Socialist "Success?"

Today's quiz question will be "What's The Problem Here?"  For reference purposes, I have placed a map of East Asia here, and would direct the reader's attention to the purple and 
yellow colored Korean Peninsula, just west of Japan.  Got it?  Good.

So here's the lead in to the question.  Once again, North Korea is going to be facing food shortages, allegedly as a result of "summer floods."  On the other hand, South Korea is facing a rice glut, 
and apparently has more rice than it knows what to do with.  Given the proximity of these two countries, isn't the weather fairly similar, such that the "floods" in the North should have done equal damage to the South - if it truly was flooding?

Isn't it more likely that the problem is exactly what it always is in socialist countries - an insistence on top-down rigid control of people's lives and property that results in a society unable to produce adequate amounts of even its most basic needs?  Of course, the elites in Pyongyang will not be going hungry or resorting to long pig dinners any time soon, but that's also the nature of socialism.  Some animals are more equal than others.  Odd, though, how those very same elites always complain about how businesses in more free market oriented countries live off the sweat of their employees and customers.  Given that people - even here in the US - still flock to the Socialist Ideal, it just proves some of those good old adages, like how you can rob somebody blind if you yell loudly enough about how big a crook the other guy is...or how you can fool some of the people all of the time.

So.  Two countries, one a fairly free market with a rice glut, and one rigidly socialist facing famine yet again.   Similar climate and weather between the two.  Thus the question:  What's the problem here?  Fickle weather gods?  Or just crappy-as-usual Socialist "planning?"  

The quiz will be graded on a curve, no points will be given for partial answers.
