Historic Churches of Rural Georgia

After perusing the Historic Churches of Rural Georgia, I am left with the question how it happened that in one generation, less than a hundred years, a modest self-sustaining culture was destroyed and replaced by gaudy plastic and electric lights. It was not industry that produced the throw-away society and substituted quantity for quality. People did that; people who are into glitter without substance.
Why was that permitted? Encouraged, even?
Here is an addendum to the original collection.
