People have been complaining about the decline of their current cultures for millennia, looking nostalgically back at older days (and ignoring the flaws of those older times in the process).
"A tablet from ancient Assyria, about 2800 B.C., has been found that states: 'Our earth is degenerate in these latter days. There are signs that the world is speedily coming to an end. Bribery and corruption are common.' More than 2,000 years later, Socrates complained, 'Children are now tyrants...They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize over their teachers.' And Plato wrote of his students: 'What is happening to our young people? They disrespect their elders, they disobey their parents, they ignore the law. They riot in the streets inflamed with wild notions. Their morals are decaying. What is to become of them?'"
