What is Different About the Past 2 Decades of Job Recovery?

Looking back several decades at job recovery from a recession, you would note that job growth, particularly in the foundational private sector, was robust in the 1970s and 1980s. Since then, private sector job growth has been anemic in recoveries. When you have a two-decade pattern such as that developing, one has to ask structural questions. What has changed in the last two decades, compared to the previous decades?

And, oh by the way, since we are looking at a two-decade sort of problem, it would be naive to suggest we can magically remedy the underlying problem or problems in a short period of time. Something other than "just a recession" seems to be happening. The issue is "what is happening?"
