From Dr. Michael Hurd's Daily Dose of Reason:
"The spiritual crisis is psychological in nature. It stems from the fact that people don't know The spiritual crisis in America today is not from a lack of religion, or a lack of government programs. The spiritual crisis is psychological in nature. It stems from the fact that people don't know why life on earth, and specifically in America, is, and should be, a great thing. Despite this spiritual crisis, much is still great in the Westernized world. Therein lies the hope."
I would argue that religion is one of the main causes of said 'crisis'. Our self/mind/soul is all we possess, but we are ceaselessly told to sacrifice all our wants/desires/thoughts and place faith in other's or place it in an alleged 'higher being'
