Now that the supermarkets mostly "won", local bakers, greengrocers and butchers etc are usually cheaper and far better stocked than any of the supermarkets yet of far higher quality. Supermarket prices just aren't competitive any more, as they mostly stopped trying, though of course they beat the open all hours corner shops. Cut price Aldi are now the fastest growing supermarket in the UK. Tesco are laughable on price and quality by comparison with Aldi or Lidl.
There's also an element of having to prefer the one stop shop of a supermarket thanks, in part, to most of us having to have both partners working to survive. I strongly suspect if more couples were still able to support a home and family on one income there'd be many more of those butchers, bakers and greengrocers around and still thriving.
Still, we are where we are, and probably stuck with it.
tho only the rare & remarkable ppl are at the leading edge of that (as is the case with anything else in society)
During my days of play we never were around businesses though we did occasionally see retired people most of our limited oversight was mother based.
For me, this was early 90s in a big European city, there were zero shops even near where we were playing outside most of the time. So sure, this was after school and being 10-14, but it wouldn't really matter (for this topic) if there was someone at home, because most days I'd be outside just after school anyway.
this mega-problem of there being insufficient spaces for play in our current society is undeniably a human crisis (tho this likely has always been the case as 'play' as a concept is relatively new in the history of ideas)
if or not there's less overall spaces for play relative to the past is unknown, and it would seem supa difficult to get data on. but if anyone has extensive evidence on the topic, i'll like to see the links
it's likely accurate that most places in 2019 has this problems (that kids dont play outside). but there are also places, including within cities, where kids do run around and play on the roads
i'd say the contingency of this affordance is based on how good of an area you live in to be able to give this privilege of play to kids, as well as everyone else in society
The local shopkeepers and retired would keep an eye on the local kids too. If anything we'd be more likely to be pulled up and ticked off by the old lady doing her gardening or the old fella taking the dog for a walk than the local mums. The mums were often busy with the youngest of the family, cooking, and other jobs keeping them inside. Not all had toddlers of course.
The local shopkeepers - newsagent, butcher, baker all knew our mums as they were in every week so if we pushed too far it was certain to get back home. Everyone seemed to know everyone else. A non-automated surveillance state. :)
So what did we kids do? Went and played on the demolished old factory site, along the canal, or on the disused railway station and line. No one got to keep an eye on anyone there.
The situation of women having to work is just as repressive of women's rights as not allowed. I'm sure there's a lot of women, and some men, who would stay home with the children whilst young if it were possible. The expectation now is they have to juggle both.
