I think you might be referring to the quote falsely attributed to Socrates by the mayor of Amsterdam:
"The children now love luxury; they show disrespect for elders and love chatter in place of exercise. Children are tyrants, not servants of the households. They no longer rise when their 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."
