Here are a few quotes from the past. It should really highlight that the same things are said about new generations by past generations and are meaningless:
“I see no hope for the future of our people if they are dependent on frivolous youth of today, for certainly all youth is reckless beyond words… When I was young, we were taught to be discreet and respectful of elders, but the present youth are exceedingly wise [disrespectful] and impatient of restraint” (Hesiod, 8th century BC).
“The world is passing through troublous times. The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they knew everything, and what passes for wisdom with us is foolishness with them. As for the girls, they are forward, immodest and unladylike in speech, behavior and dress.” (Peter the Hermit, 1274 AD)
“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?” (Plato ~400 BC)
“The children now love luxury. They have bad manners, contempt for authority, they show disrespect to their elders…. 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 are tyrants over their teachers.” Socrates
