Yep interesting article. The term "market forces" and the naive use of statistics dresses up economics as science. But economies and markets are human creations. Markets are driven by human behavior, not some natural force.
In a PBS documentary about the market crash in 1929 one really key point was made regarding the perception that the depression started with the market crash. In fact, most of the country, the rural majority of the nation had been mired in hard times for almost a decade and there was no capacity to sustain the shock to the market crash. People naturally stopped spending which made the markets fall even more and created a huge number of unemployed. It all started when well off people in cities ignored what was going on in rural districts.
