Before, every industry had to find food and distribute them on their own. Although distribution began again, the grains distributed were mainly for cattle, and wasn't enough to support the people. As soon as the distribution began again, the government tightened policy against the black markets, and it began restraining people from freely selling goods. Because great amounts of foreign aid go into the hands of the upper class, the price of grains at the black market has decreased compared to 2 years ago. Still, as can be seen from the prices presented in the film, it is still far out of the reach of the commoners.
People continue living off the black markets.
The people would rather be able to freely do business at the black market than wait for food distributions. The other change is the complete revival of the secret police. When the food shortage became critical during 97-98, the threat from the secret police towards citizens weakened, and they almost lost faith in their strength. But the food aid completely revived them. The biggest change is that Kim Jong Il's secret plan to hand over his dictatorship to his son, Kim Jong Nam, has already began taking place.
