The free market works?

Failures in the free market were not responsible for the great depression in the US. It was due to an influx of people taking out loans to immediately put that money into the stock market that caused the crash. The free market would've corrected itself. Agree/disagree/discuss.

I don't want to denegrate the free market but I dont think it works as well as libertarians would have you believe. There's a huge gap between what people want and what they get. For example, I want all video games to be 2D instead of that 3D shit, but 2D has died.
