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.
