OP,
Perhaps what you are really seeing is the removal of the fog that kept certain negative things hidden. With the exception of a few areas and some spikes, violent crime has decreased over the decades, abortions (medical and chemical) are down, as are a whole host of things.
However, the news media brings the more shocking negative things to the forefront because it makes money. May I also suggest that reductions in religious practice could simply be fewer people “faking it” for social reasons?
