Older folks have been saying that about younger folks for centuries.
The children now love luxury; they have bad manners, contempt for
authority; they show disrespect for elders and love chatter in place
of exercise. Children are now tyrants, not the servants of their
households. 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 their teachers.
-- attributed to Socrates by some guy named Plato.
ETA, I found more:
I see no hope for the future of our people if they are dependent on
the frivolous youth of today, for certainly all youth are reckless
beyond words. When I was a boy, we were taught to be discrete and
respectful of elders, but the present youth are exceedingly wise and
impatient of restraint.
--- Hesiod, Eighth Century B.C.
"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
I teach boys ages 15-17. Sure, lots are lazy, but look at the people of our generations. Lots of US are lazy, too.
