Might be different in Australia vs the US, but the white kids here are definitely more "free range" than the Asians.

That's not too say they're not helicoptered too, but Chinese parents are a whole other level.

Think strapping a 3-4 year old into a high chair and handfeeding them, or scheduling every waking moment of a primary school kid's life.

Upper middle class Indian parents in India can be complete control freak helicopter parents too. Much more than the less wealthy ones.

I have seen and experienced some real extremes there.

I personally don’t see its being a case, based on my observation.

There is this town nearby where I live - super white, gives old money type of vibe, very expensive real estate. It’s full of free range kids running around on the streets.

It was shock to me to see it, after our diverse suburb, where kids pretty much either locked at home doing homework or at classes all the times.

So in my opinion there is definitely a cultural aspect of it.
