Imagine that. One Communist country unable to feed its own people is unable to provide enough food to help another Communist country feed it’s people.
When central planning measures all outputs in tons, there's not much incentive to design a pocket calculator. A nice ten pound desk calculator with a big crank suffices...
Forgive me, but have you been living under a rock since 1991? Not only is Russia not Communist anymore (not even CLOSE), but they don’t have any problem whatsoever “feeding their people”. I’ve spent a significant amount of time in Russia (and am actually here at the moment). Food is absolutely, positively, not a problem here. They have everything from the traditional local markets, to the neighborhood groceries, to the super/hyper markets just like we have. Every single one of these places is packed from floor to ceiling with food.
