As I mentioned, it was two working parents and the move to surburbia. (Well, I said non-walking-friendly neighborhoods, and didn't elaborate). This was what changed.
These suburbs, often designed after 1950s, were designed for car travel, rather than walking or biking. Many suburbs are designed with streets as fractals, often without sidewalks. It might be a "safe" subdivision, but there was a real risk in being run over by cars. Kids living in suburbia had to be driven everywhere for activities.
It's no coincidence that the kids growing up in that environment and coming into adulthood have increasingly moved to gentrified neighborhoods (the ones designed for walking). There has been a decline in buying cars. Whether that means allowing the kids to have free play remains to be seen. (But I suspect, things like the popularity of the books, The Dangerous Book for Boys, The Daring Book for Girls are indicative).
