Kids in the 60s and 70s respected their parents, the girls weren't allowed to wear pants to school, there was church in the school. Most importantly they saluted the american flag at school. Most kids walked to school.
Kids in the 80s and 90s had video games to play, watched more TV, had VCR's. The took a bus to school. Did not get hit on the hand with a ruler by the teacher.
These are a few things that I can think of off the top of my head.
