Hi blondes yea we seem to like the same shows (on that note any Netflix recommendations - my favourites that I re-watch are all disappearing 
)
I find programmes like this interesting if they're done well.
I followed child of our time though u think that's done now as the "kids" are mostly adults now.
From real life observation I don't think household income is an indicator BUT I have noticed that larger families the children tend to be more independent (out of necessity?)
It's just me and dd at home but I am (compared to my friends and especially where we're living now) an "older mum" plus my parents both were the eldest of big families so they were expected to help out and expected the same of my siblings and I. ("Only" 3 of us) and we tend to do what we know don't we? Usually? Or at least try and pick the best of our parents parenting.
I also was "blessed" with a fiercely bloody minded and stubborn independent child!
From about 2 she was shoving me away and "me do it" - murder! The one thing I insisted on was buckling her into car but she did a lot herself even at a young age.
She asked to be shown how to "proper cook" when she was 8/9 - we'd don't the usual baking bits until then but then she wanted to know how to cook dinners.
Then when she started high school she became a fussy bugger over uniform - Eg 2 jumpers that looked and felt the exact same to me weren't to her and there were loud arguments heated debates when I washed the "wrong one" culminating in one weekend where I taught her how to do her own laundry. She was quite chuffed she picked it up quickly and has been doing her own ever since. We have to negotiate a washing machine "rota" though 
General tidying and cleaning has been harder to teach as stuff can look "ok" until it really doesn't. And I'm guilty of that too.
But conversations with her friends revealed:
16+ year olds allowed to drink but not make hot drinks because the kettle was "dangerous" 
14+ year olds who couldn't figure out public transport timetables.
The one I had to bite my tongue was 17 yr old who'd never had sex ed (withdrawn from school classes too) but unbeknown to parents sexually active. I don't understand parents doing that.
