Delayed Perception

This ignores the fact that the economy is dynamic and often slow moving. Actions taken today might not be felt for generations.

So, do you have models which prove that actions taken from 1920-1950 were not that which was responsible for the economic climate felt from 1950-1980? Perhaps actions taken from 1950-1980 are directly responsible for what we are feeling today? And, perhaps actions taken today will be felt 20 or 30 years from now by future generations.
