Nowadays, few people deny America's decline in real or relative terms. The politicians who declare this in their campaigns find their campaigns advance. The public is well aware of the fact that America is not where it was, or where it should be.
Establishment politicians and establishment media will give the public a positive spin and uplifting scenario. You can generally count on it. This is dangerous! But, the facts and the figures tell the accurate story.
America's decline is moral! I could say this before I read the PEW study on religion and young people.
The politicians and the mainline media can't say "moral", as they would be resisted by much of the guilty populace. So, they always have to deal with the peripheral, and make their stand there; as the country winds further down the drain.
