Remember everything is learnt from state school.........
Smacking is gradually reducing in the home but school taught us about smacking by hitting/caning us. (still being done today by teachers in poorer countries) Some people arrive in this country then carry on doing it as parents.
Some parents shout, scream, belittle and humiliate, i witnessed this being done to kids in school as a volunteer, i guess when these kids grow up they'll do it to their kids.
Everything you need to be a bad parent comes from school.
If state school had made sure that some of us could read we could find out that what we were doing was wrong.
So by state school not promoting reading out loud, (which helps speech) has meant some feral members of our society have poor speech, poor reading, poor understanding, no feelings, no empathy.
There's a whole group of companies/charities/jobs etc feeding off the failure.
