..."PLEASE, GOOD PEOPLE! STOP FUNDING THIS FILTH!"
If there were enough "good people" in America today, none of this stuff would sell. They wouldn't make it because there would be no profit in it. This is why the "golden age" of television and movies (and radio) were so decent. Yes, you can talk about the "Code" but that was a guideline that people agreed on, that no one really had the stomach to try to circumvent.
Then came the 1960s (though of course the origin was much earlier) and since then, it is "so cool" to be filthy. It's everywhere now, in nearly every aspect of media there is.
