It is really a great example of how much human knowledge is really just the repeating of a standardized, agreed upon orthodoxy that has little to do with reality. In the 21st century the "expert" in various forms reinforces the orthodoxy far beyond the 20th century.

Economics can't even catch up to the 1980s and dynamic systems.
