In Boro Park many of these wives do not have a car. Either for practical purposes (can’t afford a second car or for those who live in Boro Park, it is hard to find a place to put it. Plus there are some chassidim that feel it’s not appropriate for women to drive) or ligistics. So what most women do it get the stroller and walk to the corner grocery. Most will deliver, but you still have to go down to pick out what you need. Plus if the husband is working all day, someone has to go to the post office, buy paper goods, wine for Shabbos, stockings for the girls (that wear out faster) shirts and pants for the boys and so on. Many husbands don’t get home until much later.
I feel their frustration, but still don’t condone it.
