The 30 year olds from the 90's actually did act like real adults compare to the now a days 30 year olds?

I am starting to agree with 60s year olds people in their 30's are dumb and immature they should go to a mental hospital. I just can't I've literally seen people my age throw tamper tantrums in public and nagging so much is it just me or back on the 90's people in their 30s were more civilized and normal?
