Christ people, the government controls 'the economy', and is always responsible for everything that happens in it. We impose a sort of capitalism on society, which inherently gives very bad results for many people all of the time, and even some of the people that matter once in a while.
But if you notice they're not jumping on the reform bandwagon.. keep in mind that status is relative, so having one billion in a depression is just as good as having 10 billion in good times.
Anyway - capitalism (the government) is to blame.
The winter's gone, the summer came, glory to the Communist Party for this achievement!
