Not sure if your question "What do you suppose it will take for people to 'wake up' to this truth?" was meant to be purely rhetorical or not. My reply would be: The same thing it typically takes for people to wake up to the importance, power and reality of the unconscious and our inner needs. Namely, some sort of crisis--psychological, spiritual and/or physical--is often what spurs us to start taking the truth of our inner, spiritual needs seriously and valuing things like sleep, quiet, solitude, comtemplation and introversion at least as much as outer material and worldly pursuits such as wealth, power, success and consumerism.
