Another reason that the authorities don’t care is that their bosses, the politicians, often partake in child sex abuse as a hobby (cf. Jeffrey Epstein and his very close links to Prince Andrew, his links to Donald Trump, and his acquaintance with Bill Clinton... that’s not all coincidence there).
Popular news stories aren't representative of the real world. There's no sense trying to imagine some cohesive picture of the world from them. It's like somebody discovering a mutant shark with two heads and saying there's less fish in the ocean because sharks have too many heads and are eating more than their fair share!
