MA: Alas. I noticed that about disposable utensils and dinnerware.
Disposables makes life and keeping Kashrut esp. more manageable for frum families.
Otherwise some families need two dishwashers. If they’re lucky to afford them and the space and costs of running them.
Also, one side of a double sink is tiny and dishes can pile up quickly.
And think about babies today … disposable diapers.
Imagine how much work it was to wash cloth diapers. Some people still use them. That is intense labor. Today diapers pile up in landfills. Yet disposable diapers are conducive to life in WEIRD nations.
Going old school may be a great setback in the longrun for families and individuals.
