Take a look at the graph about about Industrial Production in the United States. What letter does this remind you of? A "V" perhaps? Well, this V is not for Vendetta. It's for getting people back to work. A V-shaped recovery. When there is a recession, machines can be turned off or turned down. When the recession begins to lift, then the switch can be flipped and they roar back to life. If our economy was based off of machines, then the employment would look a lot like the chart above. But it doesn't:
Many economists don't believe that we are in a structural unemployment cycle and instead argue that the lack of aggregate demand is why unemployment is still so high. I am not as convinced. Mainly because I don't believe these are mutually exclusive problems. That is to say, I am of the belief that aggregate demand is too low AND there is a skills mismatch.
