How far has the economy really come since 2008?
This rather complicated image from here is actually quite telling if you take a minute to study. The black line is the supposed normal long run level for each indicator. The red line indicates when QE began in 2009, and the blue is where we are today.
In summary not much has changed and despite the month to month improvements, the relative improvement to where we were prior to 2008 is immense.
