Lots of parents are definitely softer now, there was a thread recently about a child being badly behaved & the op kept saying I ASK them to stop doing... I do ASK them to sit down...when my daughter was naughty I TOLD her to behave & my mum just had to give me THELOOK!
Oh yes, I was raised to fear my parents as well.
It did wonders for my self esteem and helped me find myself in healthy relationships - nope
I don’t want anyone to hit their child, but when I’m sitting in a coffee shop I do want parents to keep their child under control -that means sitting down, not wandering around annoying everyone
have coffee at home 
I'm in my 60's - kids used to get smacked for misbehaviour when I was one. And they got caned in school. In general I think that people were more in awe of authority then - we were brought up to be afraid of policemen, teachers etc. These days parents kindly tell their kids how nice everyone is, and kids can't be punished in any painful way, so they do tend to get away with more than we did.

I'm pretty sure that if I'd played up on a plane ( or a train in those days ) I'd have got a very painful smacking . I'm not saying that was a good thing, but pain did have an effect on badly-behaved kids.*
Jesus wept 
We were raised in a very strict household and had "the fear"
I can guarantee that there were tantrums and that we were all rebel teens as a consequence. We were quite smart about it though and my parents had little clue. We lied and did everything in secret. And this continues now, the secrecy
. My parents have always lived not knowing us at all.
To everyone else, perfect children, how well they behave. When the sun went down... This was the norm in my town. Well behaved private girl school... just an image
We decide to forget the bad behaviour, so rose tinted all the way
