It's already begun (the collapse of Western Civilization).. and there will be no part of it left unscathed.. economy, culture, govenance, civil peace, science & technology, education.
The glue that holds civilizations together is faith, family, procreative vitality, institutional integrity to its founding principles. All of those have been layed waste by the New Age Culture, with its antithetical babble of relativism and gratification, that has taken over the West with breathtaking speed in the the last 45 years.
A civilization is defined by its written constitutions, laws, testaments, treaties defining a comprehensive moral vision of the society . None can survive on the nonsense and sophistry that now dominates the public ethos and conversance. That will utterly undermine and fragment all of its sustaining structures from below.
