Hot take: a lot of people complaining about how manufacturing has gone down the shitter and nothing lasts anymore have simply changed their buying habits in line with newly available products.
The stuff nanna used to buy that lasted 50 years is still available.
You can still buy a hand spun jumper, a hand woven blanket, a handmade pair of shoes and a hand forged knife. They cost a week's wage. Exactly like back in nanna's day.
"the kmart shoes don't last, not like back in my day"
There has been no day ever when a pair of shoes that costs less the a loaf of bread has lasted more than 20 minutes.
